'Cannot create unknown type' error in Orchestrator


My process is working well when it starts using studio but if starts using bot, it occurs error.

Error message appears in orchestrator like follow:

Cannot create unknown type ‘{clr-namespace:BalaReva.Externals;assembly=BalaReva.Externals}UnZipFile’."

that log is exception.message.

How to handle this error?

Best Regards,

Hi @suhyeon

The Robot is not able to download the custom package. You will need to copy the packages from the local Studio feed to your Robot feed.

Hi suhyeon,

Download the Package from uipath gallery and paste into the C:\Program Files (x86)\UiPath\Studio\Packages

then install Package from Local


make sure your package available in the local
and then publish the code before that remove the project .json file
