Nice, that totally makes sense not to log it as an error! However, I would like to use something else here, with the newest ory/x release we have added an AuditLogger (https://github.com/ory/x/blob/master/logrusx/logrus.go#L138) which will be responsible for logging auditable actions (e.g. access denied, access allowed, ...) in the future. It's currently very similar to the existing logger but adds a field audience=audit to the structured log output, which can then be used to filter in your log pipeline. I would prefer to move to that than to ignore the error completely!

@aeneasr I added audit logger and use for allow/denied access. Could you review again?
