Hi @mokeefe
Welcome to the Auth0 Community!
Seeing this is related to SAML requests/responses that would need to be analyzed, please submit a Support case with our team. A HAR file will be required in this case and we are not able to securely process it, whereas our Support agents will be able to provide assistance with this issue.
Please don’t hesitate to reach out to us for any future inquiries, have a great one!
