We classified this failure as an environment state issue rather than a code change. The failing task (tanstack-solid-start-e2e-basic) is unrelated to the PR's touched project (@tanstack/router-core), and the root cause is a port conflict (EADDRINUSE :::37551) where another CI process occupied the port before the test server could start. A rerun of the pipeline should resolve this.
Self-Healing CI
Classification: Environment state
No code changes are applicable.
The failing task tanstack-solid-start-e2e-basic:test:e2e--vite-ssr--shard-1-of-4 was not classified as a code change for the following reasons:
Unrelated project: The PR only touches
@tanstack/router-core, while the failing task belongs totanstack-solid-start-e2e-basic. There is no code relationship between the PR changes and the failing test suite.Port conflict error: The failure is caused by
EADDRINUSE: address already in use :::37551. This is a CI environment issue where port 37551 was already occupied by another process before the test server could bind to it — not a logic or code error.Zero flakiness rate: The task has a flakiness rate of 0%, ruling out a non-deterministic/flaky classification. Combined with the unrelated project, this points to a one-off environment state issue.
No similar failures on main: The
similar-task-failure-detectorfound no matching failures on themainbranch, confirming this is not a pre-existing regression introduced by recent changes.No fix possible from code: Since all downstream test failures stem from the server not starting (connection refused to localhost:37551), there is nothing in the PR diff that could be changed to resolve this — the fix requires the CI environment to release or reassign the port.
