What happened?
The configured credential type is not compatible with the requested authentication mode. For example, a client secret cannot be used with mTLS Proof-of-Possession orSendCertificateOverMtls because mTLS requires a certificate
to bind the token to the TLS transport.
Mitigation:
Use a certificate-based credential viaWithCertificate(),
or a delegate that returns a ClientSignedAssertion with a
TokenBindingCertificate when mTLS Proof-of-Possession is required.
