I've integrated Okta as an external OIDC IDP in B2C custom Policies. I got the following error after logging in to the Okta and got redirected back to my .net core application.
Message contains error: 'invalid_request', error_description: 'AADB2C90238: The provided token does not contain a valid issuer. Please provide another token and try again.
', error_uri: 'error_uri is null'.
What are token & issuer which are mentioned in the error.
