Environment
gh aw version: v0.76.1- Proxy image:
ghcr.io/github/gh-aw-mcpg:v0.3.19
- GitHub host: GHE Cloud with data residency (
sj.ghe.com)
- Workflow:
repo-assist
What happened
The agent job fails immediately after the DIFC proxy starts. The Copilot agent
process never launches (/tmp/gh-aw/agent-stdio.log is never created) and the
MCP gateway PID is never captured.
The last line before exit code 1 in the agent job logs is:
HTTP 404: 404 Not Found (https://localhost:18443/api/graphql (https://localhost:18443/api/graphql))
The proxy starts successfully and correctly routes REST (/api/v3) — the
pre-run bash step completes fine, fetching issues and PRs. But the Copilot agent
binary fails when it first hits the GraphQL endpoint through the proxy.

Gateway may not have been started or PID was not captured
Expected behaviour
The DIFC proxy should correctly forward GraphQL requests to
https://copilot-api.sj.ghe.com/api/graphql (or the appropriate GHE endpoint),
the same way it does for REST requests.
Steps to reproduce
Run any workflow on a GHE Cloud data residency instance with engine.api-target
set to copilot-api.<enterprise>.ghe.com.
