Is`OktaCredentialsProvider.handle_saml_assertion` compatible with SageMaker instances?

Inizia in redshift_connector/plugin/okta_credentials_provider.py, all'interno di handle_saml_assertion, in particolare alla riga 158, e confronta la gestione della risposta tra una macchina locale e SageMaker. Conferma se la risposta di SageMaker può essere gestita in modo compatibile e documenta un test riproducibile o il comportamento previsto per la correzione.

I'm encountering an issue when using redshift_connector with Okta-based authentication inside my organisation's SageMaker environment.

In OktaCredentialsProvider.handle_saml_assertion I receive an error okta_credentials_provider.py#L158 despite receiving a 200 OK and a response of length > 2k.

Upon investigating the logs it seems to be down to a browser or Javascript issue? I've tried on both SageMaker Studio Code Editor and SageMaker Notebook instances and get the same issue.

It's also strange that OktaCredentialsProvider.okta_authentication works perfectly and I'm able to retrieve the okta_session_token, but the later step fails.

The same identical code works perfectly on my local machine.

I've attached the relevant part of the response below:
