   * `unsupported_credential_format`: Requested Credential Format is not supported.
-  * `invalid_proof`: The `proof` or `proofs` parameter in the Credential Request is invalid: (1) if both fields are missing, or (2) both are present simultaneously, or (3) one of the provided key proofs is invalid, or (4) if at least one of the key proofs is not linked to a required `c_nonce` value (refer to (#nonce-response)).
