I see this instruction when using lock.js to enable app to support the post back that SAML does after SSO login
But this does not apply to the auth0-react setup I have apparently. I am not sure what to do when I am using auth0-react. We got SP initiated login to work fine but IDP initiated fails after we try to redirect to these request/response flows:
So, as of now the callback happens after SSO SAML, then step 3 fails as 405 method not allowed because my application likely is not ready to handle this POST callback
So what do I do in my auth0-react app to fix step 3?
