Hi @luchovelez

This error is being faced a lot from some days, the only solution that I found was to degrade activities package version and kept on trying till the perfect fit of packages work on the VM.

Hi,

This looks like the same issue described here: Issue with 2023.4.0: Unable to run code on robot machine: "Could not load file or assembly 'UiPath.System.Activities, Version=23.4.2.0"

It should be fixed in the 23.4.1 patch. If it isn’t please let us know.

Thanks!

but i don’t have problem with activities packages is for document understanding activities is so annoying

8

not was resolved is a big bug

9

i am using 2023.4.1 version

10

It is coming with a lot of different packages, some how the assistant is not able to resolve the dependencies. And thus this error is coming.

Only solution right now is to degrade your IntelligentOCR and DU related activities.

11

if i downgrade that my project has activities unresolved

13

In my case it worked out, had to downgrade some of the related activities…
Let’s wait for some other responses.
But as per my knowledge the only solution right now is to downgrade the activities and keep trying to run it from Orchestrator/ assistant.
