It looks like the user agent is used by some web crawler (bytespider; spider-feedback@bytedance.com).
We can fix the parsing, but I suggest you to verify if the traffic is acceptable for you or if it would make sense to block such request.

It happens 5x in week, so the traffic should not be an issue.
