Thanks for reporting. I unfortunately don't see your logs in our system, so I'm not able to investigate the problem further. Did you use the /feedback command to upload the logs and session details? If you see the problem again, please retry /feedback and post the thread ID here.

Thanks for flagging this. To help us reproduce and prioritize:\n\n1. What environment are you using (OS, version, and install method)?\n2. What exact command or config triggers the issue?\n3. Can you share logs or error output if available?\n\nWe will update the proposal once we have the missing details.

Happened just again, did the feedback upload now?
codex installed over homebrew IIRC

$which codex
/opt/homebrew/bin/codex

[etraut-openai]

@lddr, no the feedback didn't upload. Maybe the problem you're seeing is related to a general network connectivity issue?

Haven't had any issues recently, will try again later or tomorrow. I just updated to 0.98.0 and will keep an eye on it. I'll close this issue and reopen it if it comes back again. Thanks for taking care!

happened again and I'm not 100% sure if the upload worked well, although it said it's uploaded
