bug: nes not working

[GianlucaP106]

Did you check docs and existing issues?

• I have read all the sidekick.nvim docs
• I have updated the plugin to the latest version before submitting this issue
• I have searched the existing issues of sidekick.nvim
• I have searched the existing issues of plugins related to this issue

Neovim version (nvim -v)

v0.11.4

Operating system/version

MacOS 26.3

Describe the bug

I have followed the installation steps but cant get nes to work at all. No errors or messages show. Health check returns a OK. Copilot is loaded, I have signed in to Copilot, sidekick is loaded. Tried all the trouble shooting steps mentioned in the README. However nothing appears, and running Sidekick nes update does nothing. I am using the bundled copilot lsp server from copilot.lua, and that plugin seems to be working fine. When using sidekick from lazy extras, I get the same result.

Sorry for the lack of info in this report, but it silently does not work, so I dont know what can be the issue.

I am experiencing the same issue on Linux. My LSP works as well, and proposes copilot completions; sidekick detects and attach to the LSP server. I have tried with the following code, which should trigger NES

def mean(numbers: int) -> float:
    return sum(numbers) / len(numbers) if numbers else 0

I tried with other codes too, and also to trigger the NES by hand using Sidekick nes update. I don't get any errors as well

Might be #276? Pinning a commit before f8eac10 which reportedly introduced the regression (I used the one immediately before, i.e. 6b69c42) worked for me.

Might be #276? Pinning a commit before f8eac10 which reportedly introduced the regression (I used the one immediately before, i.e. 6b69c42) worked for me.

Thank you for your help. In my case, pinning 6b69c42 resolved the issue.
