How to check the claim type following the token type?
Your token request type is urn:oasis:names:tc:SAML:1.0:assertion, so your claim type must be in format: ID4216: The ClaimType 'dk:gov:saml:attribute:UniqueAccountKey' must be of format 'namespace'/'name'. Parameter name: claimType.
And on the event 500 on the below screenshot, we have some claims which don’t match this format.

Besides, we only support these four token types:

- http://docs.oasis-open.org/wss/oasis-wss-saml-token-profile-1.1#SAMLV2.0
- urn:oasis:names:tc:SAML:1.0:assertion
- urn:oasis:names:tc:SAML:2.0:assertion
