@shibbas @dereklegenzoff csn you take a look. More reports of sessionID issues.

[amirkhaki]

I also have this issue (0.0.363,0.0.362) (doesn't look like to be a model problem as i tested with sonnet 4.5, cortex5.1,gemini3)
I downgraded to 0.0.351 and the issue doesn't exist with this version

[gizotti]

I have the same issue from 0.0.355 to latest version. 0.0.354 works fine for me.

I am on:

M4 Macbook Pro
macOS Sequoia 15.7.1
zsh 5.9 (arm-apple-darwin24.2.0)
wezterm 20240203-110809-5046fc22

I've manually tested bash --norc --noprofile with the commands that are stuck when executed by copilot and they all work fine.

@EvanBoyle @shibbas @dereklegenzoff I got to the root cause of what is making it hang in my case.

We use direnv and nix to setup our projects and what it making the commands hang in my case is nix-direnv. If I remove that everything works fine. I don't know exactly why this is the case but I thought this might be helpful.

[utzuro]

I can confirm that it does now work in nix shell. I believe it worked before the update, though.

[peterbecich]

For me, Copilot CLI 0.0.365 and 0.0.367 both result in errors such as

   Invalid session ID: 1. Please supply a valid session ID to read 

when the shell is configured by direnv allow.

@marksisson , I have found a work-around. I am using a nix develop shell. Entering the nix develop shell, then copilot, does not have the issue. This removes direnv from the equation.

[peterbecich]

The original post in this thread does not mention direnv at all. I am opening a new thread for direnv specifically. I strongly suspect this issue #731 is caused by Zshell and direnv in combination: #731

[chazchandler]

I think the zshell/direnv combo is a red herring. I'm seeing this behevior in the VS Code terminal window but not in an iTerm terminal window. (edit: can't reproduce) Same project, same latest version of copilot-cli (0.0.369). I'm using nixos and devenv in both cases.

[peterbecich]

@chazchandler , what is echo $SHELL in those two environments?

[zekena2]

I have the same problem without direnv. It might be a mix of zsh and nix. I don't get any issues when I open iterm and open a bash session.

@peterbecich:

$ echo $SHELL

I haven't been able to get it working again in a regular terminal, so disregard what I said about there being a difference between terminals (vs code vs iterm). Seems like it's not entirely to do with zsh, though, since this is happening in bash too.

[peterbecich]

@chazchandler I can't reproduce the issue with bash. It works fine with bash in my test: #731
