[Posting this again as the problem still is not solved]
I am receiving the following error message while trying to run my automation using the UiPath Assistant:
For Each Email: The value cannot be an empty string. (Parameter ‘contentType’)
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.
Here are a couple of screenshots:
