Hello,

It’s most likely that the package you are using with this activity is not present on the instance of the Orchestrator, or maybe not the same version.

Upload it on your Orchestrator, or update it or, in the manage package section of your studio use “lowest applicable version” of the package.

Regards

Check this article : Cannot create unknown type - V2018.2.3 Onwards - Troubleshooting steps

Let me know if that doesn’t solves the issue.
