What happened?

I tried starting an existing workspace, but devcontainer creation fails immediately while setting up SSH agent forwarding.

Error

ssh agent forwarding setup failed:
new agent listener: listen unix /var/folders/.../T/devsy-1252726836/devsy-ssh-agent-341d40b5/listener.sock: bind: invalid argument

Exit error:
new agent listener: listen unix /var/folders/.../T/devsy-1252726836/devsy-ssh-agent-341d40b5/listener.sock: bind: invalid argument

agent exited without sending a result
Exit code: 1

What seems to be happening

The generated Unix socket path appears to be too long for macOS Unix domain socket limits. In my case the full socket path was 104 characters long:

/var/folders/.../T/devsy-1252726836/devsy-ssh-agent-341d40b5/listener.sock

What did you expect to happen instead?

Failed.
