 jenkins:
    # If you are integrating Jenkins, set its location here using the bas         


        

Answer 1

Since this question is the first SO link when searching for "No valid crumb was included in the request" in Google, I think it's worth mentioning that the same error is generated if you omit/forget the Authorization HTTP header or use a blank username/password:

Relevant error messages related to the Authorization header are only generated when a value is passed:

And, yes, the crumb passed in the first screenshots is actually valid; everything works with the correct username/password:

So, not sure if that's a bug or not, but "No valid crumb was included in the request" could also mean you accidentally forgot the Authorization header.
