(v2020.10.2) - Just upgraded to v2020.10.2 and having problems. UIPath Assistant is unable to install a package that I deployed earlier today. Just hangs for about 15 minutes and then times out. Orchestrator service is connected, and the robot is licensed. The account that is logged in has full permissions to the C:\Users… folder where the deployed package will reside. It creates the package name folder, then the version sub-folder, but that’s as far as it gets. Any help would be appreciated.

Hello, Guys good evening!!

I’m trying to compare two variables with the following condition:

Variable extracted from PDF:
NomeClienteInput

Variable extracted from AS400
NomeOutput.ToString.Trim.Equals

They really look the same.

The idea is: If they are equal they follow a normal branch if don’t they go into else branch.

Anyone with ideas to share?

Thank you guys!

Hello All,
I installed UiPath Community 19.7.0 free addition, but I am getting this no endpoint error for a whole day.

error1026×638 48.7 KB

I’ve gone through all the questions related to this error and tried almost all solutions that are suggested. Here are the few things I tried:

1. I’ve made sure Net.Pipe Listener Adapter is running
2. Turned on all features under .Net Framework from Turn windows features on/off .
3. My user account(which is not default administrator account) has administrator privileges. Also I have full control over C:\Program Files\WindowsApps
4. I’ve reinstalled several times after clearing from Roaming & Local folder.

Weirdly, I didn’t face any problem in another machine where the account is default administrator account. A note: It ran there without any Ui Robot process.

Here is the detailed error log if any one wants to see:

15:44:10.5562 => [ERROR] [UiPath.Studio.exe] [1] System.ServiceModel.EndpointNotFoundException: There was no endpoint listening at net.pipe://localhost/UiPath/service/duplex/agent/suddin that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.

I have Studio 2020.10.4 Enterprise & Orchestrator 2020.10.5

I made a tiny change to my process and published. And now I get the error below when orchestrator commands my unattended robot to run it. I tried updating all of the packages. I removed my change and re-published, same error. I committed it to Github and pulled it to another machine and published from that machine, no luck. I was able to get it working by pulling it down to the studio running on the unattended robot machine and publishing from there. Any idea what’s going on? Thanks.

Hi guys,
I have a problem consuming API orchestrator cloud with javascript, I receive error with CORS, the message is: Access to fetch at ‘https://account.uipath.com/oauth/token’ from origin ‘null’ has been blocked by CORS policy: Response to preflight request doesn’t pass access control check: No ‘Access-Control-Allow-Origin’ header is present on the requested resource. If an opaque response serves your needs, set the request’s mode to ‘no-cors’ to fetch the resource with CORS disabled.
I use the URL https://account.uipath.com/oauth/token
Thanks for any help.

Hello guys, good afternoon!

Is the following… I have a condition inside an if activity. If the condition is met it does something. If don’t, it does something else.

To start:

image904×673 71.3 KB

The condition is met but instead of following the "Then " Branch it goes into “Else” Branch.

The result:

image605×575 7.9 KB

note:
The if condition is inside the for each loop

Note: If I disable the sequence inside the “Else” Branch I will not receive any email which is Ok because the condition is met.

Anyone can help me find a solution for this?
Thank you

The process goes into a virtual machine and opens an Oracle Webforms system to search for and change a list of contract numbers. The process runs without errors, when started from UiPath Assistant, but it fails when started from Orchestrator.

The robot type is unattended, the machine key is correct, and the robot is connected and licensed.

Before failing, several selectors are passed and return no errors, but when it reaches this selector it cannot find it:
"

I have validated the selector, and it highlights the right field even though I change the size of the window. However, it still fails, when it is run from Orchestrator.

Any help would be appreciated.

Hello,

When I try to Invoke VBA in Excel Application Scope, it is throwing the error as "Invoke VBA: Programmatic access to Visual Basic Project is not trusted"

I am aware about checking the Trust access to the VBA project object model , under Macro Settings in Options in Excel .

But, if we are running the same in Production, then all the machines requires this manual change.

Is there any other alternative to fix this Error?
