Invalid SPNameQualifier for this request

[It Meme]

Hi:

I have been following University of Chicago's notes on Shibboleth
integration with Service Now (IdP v2.2):
https://docs.google.com/document/d/1yApSgHn0C02z09zYC3CD_edX7s3DbnuGgJ-kI-BhqYI/edit?hl=en_US&authkey=CPK1ppQN&pli=1

We are receiving a 'Invalid SPNameQualifier for this request' status
value in our IdP process logs - any guidance on what could have
triggered this?
