Cannot find the source of "TypeError: Cannot read properties of undefined (reading 'uri')"

[AntoineGS]

So this is pretty much certainly an issue with the way I am using the SDK but I cannot seem to figure out what uri it is reading.
Starting with version 1.279, when I go from opening the editor without an opened file, and then open a file, I get the following:

2025-03-25 21:00:05.771 [59] [ERROR]: LSP message: [default] unhandledRejection: TypeError: Cannot read properties of undefined (reading 'uri')

    at processImmediate (node:internal/timers:471:21)

Versions 1.278 and below do not have the error message.

Since it is closed source I cannot get the context of the error 🙃, if someone would be able to give me some pointers it would be greatly appreciated.

Thanks in advance :)
(The editor in question is NeoVim, and the plugin is copilot.lua)

If it's happening on open, that sounds like textDocument/didOpen. Try enabling trace logging in Neovim and look for any notifications like that and see if anything looks wrong with them. Also check for textDocument/didClose and textDocument/didChange.

[AntoineGS]

The logs do show the didOpen, however it is passing an uri.
This shows the logs from a new application instance, up until the logMessage that shows the error:

I still cannot figure out what data being passed is causing this error :(
The didOpen just before the error has a uri param.
Any ideas?

[tpope]

The logs show that didClose is being called on that document URI before didOpen. And that's exactly when the first error occurs. We should be more robust about that (I've already merged a fix) but at the end of the day I think it's just failing to cope with an invalid didClose event.

The stack traces also suggest that you are testing on 1.279 rather than the latest version. Please test on the latest so we have a common reference point.

[AntoineGS]

Right I have been playing with versions a lot to try and figure out the cause, here is an updated log for reference:

Thank you for the assist and the patch even though the issue is not on your end, much appreciated!

PS: I will be looking into sending a fix into NeoVim

[AntoineGS]

I see the new build already has the change, thank you!
