Copilot MaxListenersExceededWarning, stops working

[DylanModesitt]

After 5-10 minutes of using copilot.el, it stops working entirely. copilot-diagnose will bring it back (but only for a few minutes). A few colleagues of mine also experience the same issue. copilot-events shows

[stderr] 
[stderr] 
[stderr] nil

[stderr] Process copilot agent stderr finished

[stderr] (Use `node --trace-warnings ...` to show where the warning was created)

I have seen the same issue mentioned here in reference to copilot.vim. Perhaps this is also related to the many seeming to experience #181? My version of node is 21.7.1, npm is at 10.5.0, I am on GNU Emacs 29.2 (build 1, aarch64-apple-darwin21.6.0, NS appkit-2113.60 Version 12.6.6 (Build 21G646)) of 2024-01-18. I have run copilot-reinstall-server (no effect). Happy to provide any additional details that might be helpful.

Hi, I'm experiencing the same issue, but only for rustic-mode. Copilot works fine for C,C++ or elisp modes. I don't know what to do to help but if I can, feel free to ask. If you tell me what you need, I can can give you backtraces, logs or whatever.

I added --trace-warnings :
