Automation running on UiPath Studio but not on UiPath Assistant

[sarai.andino]

I am receiving the following error message while trying to run my automation using UiPath Assistant:

The value cannot be an empty string. (Parameter ‘contentType’).

I receive the message as soon as the automation starts with the Use Desktop Outlook App activity. There is nothing empty nor a parameter named “contentType” within this activity, nor the ones inside this scope (For Each Email → Save Email Attachments).

Is particularly frustrating as I can run the automation from my PC using UiPath Studio and it works.

Help please.
