Hi there,

I used data scraping to extract from a website a table of data.
After which, used excel application scope to create a new excel sheet called Dcon.xlsx, and write range to copy the data into the excel.

However, i keep getting an error: Object reference not set to an instance of an object. This error usually occurs when using a variable with no set value (not initialized)

I;m not sure why this is happening and have tried to search online for a solution however to no avail.
Can anyone assist?

Thank You!
Kim

Hi,

I need to move specific Excel files from one folder to another. I used MoveActivity but it is not able to understand the path. Not sure why because when I move a .txt file from the same folder it works. I tried adding an .xlsx extension and it didn’t work.

Ugh. I am unable to get the Orchestrator to function. I can identify/paste the Machine ID, but when I paste the full path of the Orchestrator into the Orchestrator Settings, it provides a pop-up Robot error message: “There isn’t an Orchestrator present at the indicated URL”

Hi guys,

So I have this robot, published in orchastrator, attached in a machine (my local machine).
If I run it from orchastrator, it works end to end without errors.
This machine is a windows 10 OS.

Then I added a new machine, an windows 7 OS 4gb RAM and linked this robot to it.
After configurating all the requirement stuffs, I’m trying to run the robot.
Soon as it starts an message error throws to the window:
Job-stopped-with-an-unexpected-exit-code-0x000000FF.

I don’t know what am I doing wrong.
I read another topic saying to restart the service, to check the screen resolution and the requirements of hardware and software. The machine fill up all this check-points.

I need to copy a files whose path length is greater than 260 characters. This works fine when you copy it normally through file explorer or cmd or power-shell. But when I try to do this from “Move File” UiPath activity it throws the long file path error. I tried to invoke power-shell and passed the command, but still it throws the same error. Can somebody help me with this?

Hi all,

I get this Job stopped with an unexpected exit code 0xE0434352 error when read a huge text file, something like 2m rows. Its not happening on small text files. Then I realized it’s because windows suspend the application, a green leaf appears near to Robot Application after some point where Robot occupy around 2.8gb on ram (My computer 8gb). I tried on different computers but still get the same error. I could not find any solution somewhere and this is crucial about my project so I really need your help. I attach exapmle photos for better understanding.

Thanks in advance

Scenario:

I am trying to invoke a workflow but it is not allowing me to, it gives the following error:

System.Exception: The invoked workflow ‘XXX’ has validation errors. Please review the workflow and resolve the errors. —> System.Activities.InvalidWorkflowException: The following errors were encountered while processing the workflow tree:
‘XXX’: The private implementation of activity ‘1: XXX’ has the following validation error: Value for a required activity argument ‘Value’ was not supplied.

The workflow invoking this one invoke other activities just fine but it fails when trying to invoke this specific.

I have had a look through the workflow but can’t see any validation errors, and when I use the “Validate” option in Studio it says “No validation errors found”.

Slightly baffled by this one. Anyone encountered anything like it before? It has the same dependencies and arguments as the other workflows that are still successfully being invoked.

Hi,

I am experiencing intermittent ‘The operation has timed out’ errors when using ‘Get Outlook Mail Messages’. Has anyone ever come across this before? When the error occurs, it does not recover on retry attempts. A log out/log in seems to fix the error.

The error sometimes occurs at the start of the process and sometimes mid way through.

It is an unattended Bot working on a windows 10 VM using Studio v2018.4.5.

Thanks in advance.
