pushing IngestInput-pprof failed invalid_argument

[hawkingrei]

I am working to make pyroscope-go into TiDB by pingcap/tidb#52139. but I find this error message. and i cannot find CPU profiler in the dashboard.

[ERROR] upload profile: failed to upload. server responded with statusCode: '422' and body: '{"code":"unknown","message":"pushing IngestInput-pprof failed invalid_argument: invalid utf8 string hex: d614508c2ea7ff1e0af4842e2d811c1eac516ac461129cf1f89d17ec148fa780"}

Hi @hawkingrei, thank you for reporting the issue! Could you please collect a profile from a running TiDB instance using the built-in profiler and post it here? That would greatly help with the investigation. Also, could you please specify which Go version you're using?
