I’m implementing my first enterprise SAML connection in addition to an existing and functioning database connection. The app uses OIDC with Auth0 and has worked fine on the database connection for a few months.
When using an IdP-initiated session over the enterprise connection, the users are created in Auth0 fine, but on the final redirect by auth0/resume to my application callback URL, we inexplicably receive a GET request instead of a POST request as per the Sp-initiated DB connection OIDC flow.
I’m not expecting to handle this in my OIDC client code in the application and throw the obvious method error.
QUESTION: Is this method an issue I should try to code around in my app, a config error or an auth0 bug?
