Error Codes

IdentityServer error codes

If you make a faulty request in some way towards the auth endpoints, you will face any of the error codes below.

Error Code	Error Description
`invalid_request`	The request is missing a required parameter, includes an invalid parameter value, includes a parameter more than once, redirect URI has incorrect URI scheme, or is otherwise malformed.
`invalid_client`	The request is missing the client ID or the request contains an invalid client ID.
`invalid_grant`	The request is missing the grant type or the request contains an invalid grant type.
`unauthorized_client`	The client is not authorized to request an authorization code using this method.
`access_denied`	The resource owner or Visma Authorization Server denied the request.
`unsupported_response_type`	The Visma Authorization Server does not support obtaining an authorization code using this method.
`invalid_scope`	The requested scope is invalid, unknown, or malformed.
`server_error`	The Visma Authorization Server encountered an unexpected condition that prevented it from fulfilling the request. (This error code is needed because a 500 Internal Server Error HTTP status code cannot be returned to the client via an HTTP redirect.)
`temporarily_unavailable`	The Visma Authorization Server is currently unable to handle the request due to a temporary overloading or maintenance of the server. (This error code is needed because a 503 Service Unavailable HTTP status code cannot be returned to the client via an HTTP redirect.)
