Description

GitHub Copilot Enterprise provider fails to initialize after following the troubleshooting steps for re-authentication. The provider was working previously but now throws a ProviderInitError when attempting to run any commands.

OpenCode version

1.0.132

Steps to reproduce

1. Logout from GitHub Copilot Enterprise:

opencode auth logout
# Selected: github-copilot-enterprise (oauth)

2. Clear opencode data directories as per [troubleshooting docs](https://opencode.ai/docs/troubleshooting/#provideriniterror):

rm -rf ~/.local/share/opencode
rm -rf ~/.cache/opencode

3. Re-authenticate with GitHub Copilot Enterprise:

opencode auth login
# Selected: GitHub Copilot > GitHub Enterprise
# Entered GitHub Enterprise URL
# Completed device flow authentication successfully

4. Set default model in ~/.config/opencode/opencode.json

`"model": "github-copilot-enterprise/gpt-4.1"`

4. Attempt to run a command (or ask question in opencode):

opencode run "test"

Application crashes with ProviderInitError:
