Hi, everyone

I am trying to build pipeline to automatically update my automation using github. I followed this video while trying to build that. But unfortunately, it stucks in “Build” section. I’ve waited for hours but it doesn’t change.

This is video I am following: Automate Deploys with UiPath Automation Ops Pipelines | CI/CD (Full Tutorial) :rocket: (youtube.com)


For the picture above I enter this information:

OrchestratorUrl (String) :

cloud.uipath.com/organization_name/DefaultTenant/orchestrator_’
(It has https:// in the beginning)

OrchestratorFolder (String):
Production

In the Pipelines folder I created this Robot user as showed in the video:


What’s wrong? Could you help me?

Error Loading Microsoft.IdentityModel.Token

$

Hi Everyone,

I need help, I have a problem at starting UiPath’s robot, instead of opening it, appears this error message, and it does not allow me to see the scheduled activities.

An error message indicates that the type 'Microsoft.IdentityModel.Tokens.Configuration.LKGConfigurationCacheOptions' could not be loaded from the assembly 'Microsoft.IdentityModel.Tokens, Version=6.14.1.0'. (Captioned by AI)

I’ve tried changing the version of some packages, and it shows me the code, but when I run it I get errors in certain activities (click images for example). Restarting UiPath doesn’t solve the problem.

How can I fix it?

Thanks in advance.

Intermittent error - open file timed out when invoking workflow during robot run

$
0
0

We started encountering an intermittent error on our robots that is happening while invoking a workflow. I can’t find much information about the error but it seems like a timeout occurs when opening a local project file. The system exception reads “System exception at initialization: OpenFile timed out. at Source: UiPath.CoreIpc”. It will happen at different parts of the code, usually during initialization and more rarely during processing a transaction. When the logs are more detailed, I can see that it failed on a certain xaml file which is stored on the local machine.

I know this isn’t a lot to go on but hoping someone has experience with this and can offer insight. UiPath told us to update our dependencies which we did and still facing the same issue. We started seeing this error close to the time we upgraded Orchestrator from a 20.10.xx version. I don’t have the exact number right now and not sure if relevant…

When does error occur: unattended robot jobs
Robot and Studio version: robot 22.10.13, studio 22.10.13 with system.activities 22.10.18 and Windows legacy (old robot 20.10.14, studio 20.10.14 with system.activities 21.4.0)
How often does the error occur: intermittent, can happen in batches or one off then not happen for days
Orchestrator version: 22.10.7

Windows event viewer error message:
UiPath.Service.Host 22.10.13.0
UiPathRobotServices 39889609 IExecutorContract OpenFile 52. # System.TimeoutException: OpenFile timed out.

Error en Action Center

$

Buenas comunidad, Vengo a publicar un problema que estuve teniendo en los ultimos dias con el Action Center en el Cloud de UiPath.

En mi automatizacion creo tareas para atenderlas en Action Center y utilizar la herramienta como validacion de datos.
Para ellas las levanto desde un proceso hecho en Studio Desk

El error puntualmente consiste en:
Levanto tareas como siempre, pero esta vez no me cargan las mismas y me tira error congelando la pantalla.

Consideraciones:
Esto no me sucedía la semana pasada, podía subir las tareas, revisarlas y completarlas sin problema.
Realicé cambios en las mismas agregando campos, comencé a tener estos problemas, deshice los cambios y los problemas persisten.
Las tareas viejas puedo abrirlas sin problema, son las nuevas las que ocasionan el error.
Estoy trabajando actualmente con la version Comunnity

Si alguien tiene sugerencias o informacion al respecto, les quedare agradecido.

Saludos comunidad!

Handling Dynamic UI Selectors Across Environments in projects

$
0
0

I’m working on a project that relies heavily on UI automation, but I’m facing an issue where the selectors change across different environments. For example, selectors in the dev environment are different from those in the testing environment. As a result, whenever I move the code between environments, I have to rework all the UI elements, which is quite time-consuming.

One idea I had was to create a selector configuration setup to handle this. I’d love to hear your thoughts—do you think this is a good approach, or is there a better way to manage this?"

When I try to RUN the project I receive a below error. Could not find the user-interface (UI) element for this action

Hello,

I can not RUN the project. Everything goes well , I can complete all the steps without error , but when I try to RUN the project I receive a below error. I tried multiple times to find out the problem at activity :Type Into, but i don’t find a mistake. Could you please give me an advice?

Thnak you in advance,
Andreea

Something went wrong with the Application .
Activity Type Into ‘DIV’ ( N Type Into ) failed:

Could not find the user-interface (UI) element for this action. Possible solutions: • Ensure application is opened and the UI element is visible on the screen at execution time • Edit the Target of the UI activity and use Validation to debug the issue. • If needed, re-indicate the element as its properties might have changed • Use “Check state” activity to check the application state before executing the action • Increase the “Delay before” value to allow time to the application to render entirely and become responsive

Issue with LLM Call in Agents Solution – Prompt Works in Content Generation but Fails in Agent

$
0
0

Hi,

I’ve been exploring the Agents Solution in UiPath, and I recently encountered an issue with how it handles LLM calls.

Specifically, I noticed that a system prompt that works perfectly with the Content Generation activity fails when used in an Agent. I tested the same prompt directly in Claude and ChatGPT, and it worked as expected in both cases.

Below are screenshots showing the different behaviors:

Error when using Agent (Anthropic and ChatGPT):

Successful result using Content Generation activity:

From my observations, it seems the Agent may be attempting to force a tool call in the background - possibly a behavior introduced by UiPath. This could be causing the prompt to fail under Agents while still working normally in other contexts.

I’ve attached the system prompt I used for your reference:
prompt.txt (6.0 KB)

Let me know if you need any additional details.

Delete file System exception

$
0
0

Hi,

I’m seeing the error “The process cannot access the file “File name” because it is being used by another process.”

The bot executes the delete activity to delete the excel file that has been created and processed in prior.

I have checked in debug mode, it seems the excel scope activity is closing the excel and there is a kill process “Excel” activity too and delay of 15 seconds before the delete activity, still the above mentioned exception is displayed.

In debug mode What I saw was after excel scope activity closes the excel file, I tried to open it which should open but, here there is an error in excel when opened manually says “Excel cannot open the File because the file name or extension is not valid. Verify that the file has not been corrupted and that the file extension matches the format of the file”. Please see the screenshots.

After stopping or bot completes its process steps, the same excel file opens without any popup messages from excel.

What I learn is that UiPath executor during execution of the bot somehow is not releasing the excel file and thus while deleting an excel that had been created using the bot process steps throws the above mentioned error.


Thanks
Sreekar

Why does try catch skip blocks in production?

$
0
0

I am encountering an issue with the try-catch block in production. As you can see, my program follows a flow where each “block” represents a sequence containing a try-catch block. The intended behavior is that if an exception occurs within any block, the try-catch should handle it, allowing the subsequent block to execute as planned. For instance, if block 3 encounters an exception, block 4 should still proceed. While this works correctly in debug mode, running the robot in production mode causes it to skip all blocks in the diagram upon detecting an exception. The same behavior occurs when using the “continue on exception” function in the Debugging ribbon. Am I missing some configuration that would ensure proper functionality?

Hello Team

I hope you can help me with this error.
I am using the Excecutive Query Activity because I need to run 6 different queries. The first 4 queries run without any problem, but the last two are soo big (there are joins for around 5 or 6 tables) and I don’t know the reason for this error.
I addes into the Timeout argument 60000 milliseconds but I continue with the same error.

Do you know how I can fix it?

Execution Timeout Expired. The timeout period elapsed prior to completion of the operation or the server is not responding. The wait operation timed out

You can find the activity following this path:

I am trying to generate an access token using a refresh token. I have inputted the correct client_id and client_secret values but when I try de-bugging my process, I keep getting the “Error: invalid_client”

I have set the scope for client_id and client_secret to global since I am using the same to generate a refresh code.

I’m using UiPath studio instead of postman/orchestrator since I am a student and this is our project

Unexpected error has occurred during the library compilation process: The assembly compilation returned the following errors: * Value of type 'String()' cannot be converted to 'File'. * Value of type 'File' cannot be converted to 'String()'

$

Hi everyone,

I’m encountering this compilation error when trying to publish my framework:

The assembly compilation returned the following errors:
 * Value of type 'String()' cannot be converted to 'File'.
 * Value of type 'String()' cannot be converted to 'File'.
 * Value of type 'File' cannot be converted to 'String()'.

image

The issue is: I’m not sure where in my process this type mismatch is happening.
My project is quite large, and manually checking every argument, variable, and activity isn’t very efficient.

Before I dig through the entire workflow step by step…

:red_question_mark: Is there a way to precisely locate which XAML, activity, or argument is causing this compilation error?

Ideally, I’m hoping there’s:

  • A log file that points to the specific XAML
  • A setting that enables detailed compilation diagnostics
  • Or any trick to instantly find which file contains the mismatched types

The error message doesn’t indicate where the problem occurs, so I’m wondering if there’s a method I’m not aware of.

Thanks in advance — would really appreciate any tips or best practices for tracing this!
