Annot create unknown type '{}ShouldStop


I am beginner on UIPath :frowning:
My package works well, on UIPath Studio Community 2022.4.3,
But when I deployed package to orchestrator with : 2021.10.3, it doesn’t work :frowning:

I have the following error :

Thanks you a lot @Mr.StarLord_AO for your answer.
1) What package did I need to downgrade ?
2) Unfortunately I don’t have 2021 version of UIPath, I don’t have enterprise edition :’(

Like system.activities

If I downgrade system.activities, the code doen’t work, I need after to downgrade other package (I don’t know how many) :frowning:

I finally import once by once all missed library on the orchestrator, and it’s works !
