Hello

I have a project that I ran successfully on studio machine and in test machine, however
I get the following error when I try to start my job from orchestrator on another machine :

Could not load file or assembly ‘PersoOffice365Library, Version=2.0.3.0, Culture=neutral, PublicKeyToken=null’. The system cannot find the file specified.

System.IO.FileNotFoundException: Could not load file or assembly ‘PersoOffice365Library, Version=2.0.3.0, Culture=neutral, PublicKeyToken=null’. The system cannot find the file specified. at ExtractionsWeb.Main.GetImplementation()

I tried the following solution but I still get the same error

When I look at the package folder, I cannot find the library dependency, it doesn’t seem like it downloads it for some reason

2

Double-check if the robot that needs to run the job is having the same version as the one that published the process.

If the PersoOffice365Library is a custom library, make sure your robot has the source and access to download it.

3

Yes just checked it’s the same version

it is a custom library, it’s uploaded on orchestrator tenant.

I don’t know what else to try :confused:

4

Did you add these roles for your impacted robot/user account in Orchestrator?

• Allow to be Automation User, and Automation User at the Tenant level

and

Automation User at the folder level (in the folder where the process is present)

5

yes, i added this new package in an existing folder with the roles you mentioned
only difference with this new package is it runs on another machine

6

Check the Event Viewer logs for the Application and check for more details.

here are the Error messages I have in the logs:

In which mode did you install the robot (User Mode or Service Mode)?
Do you have a proxy in the impacted machine?

9

the robot is in service mode
yes correct the proxy was enabled, i deactivated it tried again and still the same message :confused:

10

Enable back the proxy, configure the UiPath.config file using this documentation https://docs.uipath.com/robot/standalone/2023.4/user-guide/redirecting-robots-through-a-proxy-server#editing-the-uipathconfig-file and in the end restart the UiPath Robot service from services.msc to apply the changes.

done but I still have the same issue…
i uploaded the package manually as temporary solution so I can run the automation but please let me know if you have any other suggestion
thanks a lot
