In the production VM Cannot create unknown type - ”

I have done coding and i have already test my code using developer VM. So that time my Bot is running fine.
But i have an issue when i’m going to publish my code on the production VM. So that time i’m facing a problem or error type [Cannot create unknown type - ”](

Can anyone plz guide why this problem is happening.

Thanks in Advance!


check the versions of the studio and robot installed in developer VM and Production VM, some activities are not able to create. This might be the one reason.



What version are your using for development and what version do the robots in production have?
