Error Codes

[fmarino-ipzs]

If the Status Attestation is requested for a non-existent, expired, revoked, or invalid Digital Credential, or the HTTP Request is not valid (missing or invalid parameters) the Credential Issuer MUST respond with an HTTP Response including the following parameters:

• error: The proper error code
• error_description: Human-readable text providing additional information, used to assist the Wallet Instance in understanding the error that occurred (e.g. some attributes are changed, revocation reason, etc.)

 HTTP/1.1 400 Bad Request
     Content-Type: application/json;charset=UTF-8
     Cache-Control: no-store
     Pragma: no-cache

     {
       "error":"invalid_request"
       "error_description": "The signature of credential_pop JWT is not valid"
     }

It could be useful to add an error code section.
