[Big Error] Http request failed with unhandled exception ...

Today, I'm creating new flow to publish new images to Pinterest. 

Then, it shows an error: Http request failed with unhandled exception of type 'ArgumentException' and message: 'The path variable 'USERID' in the UriTemplate must be bound to a non-empty string value. Parameter name: parameters'.


I searched this forum, it seems there are so many reports on this error.

Hi @jeff1102 ,


Error is from your 1st step or second step (create pin) ? if its from second step it may be issue with pinterest connector. You can raise support ticket with Microsoft for same. 




(please mark resolved if it helps you)

I have the same problem. RSS to Twitter. No matter how many times I reset it, it doesn't work. It doesn't seem to be a problem with the connector.

Existing connections work, but cannot be modified or newly added.
Connectors can be connected. I can't just create a new cloud flow.
