[BUG] [stream] Error when using bunkernet:log_stream() during preread with denied IP

[jojolll]

What happened?

Hi,

I'm observing a repeated error when using bunkernet:log_stream() in a stream context (proxying TCP connections). The client was denied during preread due to a geolocation blacklist, but an additional error was logged:

This happens during the preread phase, likely because get_headers() isn't available in the stream context — which makes sense. But I wasn’t expecting this to raise a runtime error in the logs.

Not sure if this is something that should be handled differently, or if it’s just a misconfiguration on my side. Just reporting it in case this can be prevented more gracefully.

How to reproduce?
