Error Handling

All SDK methods return a response object or throw an error. If Error objects are specified in your OpenAPI Spec, the SDK will throw the appropriate Error type.

Error Object	Status Code	Content Type
errors.BadRequest	400	application/json
errors.Unauthorized	401	application/json
errors.Forbidden	403	application/json
errors.NotFound	404	application/json
errors.TooManyRequests	429	application/json
errors.InternalServerError	500	application/json
errors.BadGateway	502	application/json
errors.ServiceUnavailable	503	application/json
errors.SDKError	4xx-5xx	/

Validation errors can also occur when either method arguments or data returned from the server do not match the expected format. The SDKValidationError that is thrown as a result will capture the raw value that failed validation in an attribute called rawValue. Additionally, a pretty() method is available on this error that can be used to log a nicely formatted string since validation errors can list many issues and the plain error string may be difficult read when debugging.
