Hope this may help you

Thanks,

Hi @Munish_Jain

Can you can try these steps:

Can you check if the FileResource property is spelled correctly and is accessible in the GetLastDownloadedFile activity and also if you are using the correct version of the GetLastDownloadedFile activity. Sometimes, different versions of activities can have different properties.
If the issue persists, try recreating the GetLastDownloadedFile activity and check if the issue is resolved.

Thanks!!

Thanks!

Hi @Munish_Jain

This can be due to Typographical error, Version incompatibility, Missing dependency, Runtime error.

  1. Double-check the spelling and case of the property name and the activity name.
  2. Ensure that the activity package version is compatible with UiPath Studio version.
  3. Check if all the required dependencies and references are added to the project.
  4. Review the workflow for any runtime errors or exceptions that may be causing the problem.

Cheers!!!

It has alot of activities… not sure how to fix it from the above solutions which are not specific…

6

As @Nitya1 mention please check this activity if all properties are valid. Try an isolated run of this activity only, if you get error or not.

Ma’am I don’t see any errors in this…

Is your issue fixed now?

Nope. I don’t get the error if I run the script through studio, but I like to run it from the assistant

Can you run and see if any error occurs or not?

Please close thread… no solution
