**Extension Version**
`v0.27.2`

**Additional context**
/

Start by reproducing textDocument/hover in extension version v0.27.2 and review the VS Code logs around the /user request and dist/server-node.js stack trace. Done means hovering over a GitHub Action no longer shows the error toaster and the logged request does not fail with connect EACCES.
