[CI Failure Doctor] CI Failure Investigation - Run #33219 #13146
Description
🏥 CI Failure Investigation - Run #33219
Summary
Go test in the test job failed because every dependency download from proxy.golang.org returned 403 Forbidden, so the packages could not be built and the test suite aborted.
Failure Details
- Run: 21566725266
- Commit: 68385cc
- Trigger: push
Root Cause Analysis
The Go toolchain attempted to download multiple dependencies (e.g., github.com/charmbracelet/bubbles, github.com/cli/go-gh/v2, golang.org/x/term, etc.) and each go command hit (proxy.golang.org/redacted) and immediately received 403 Forbidden, so no modules were available and every package reported setup failed before tests could run.
Failed Jobs and Errors
test:go test -v -parallel=8 ... ./...failed because each package’ssetup failedlog entry corresponded to aGet "(proxy.golang.org/redacted) Forbiddenerror for its dependencies.
Investigation Findings
Logs show consistent Forbidden responses from the Go proxy for every dependency the repo imports, so the failure is an external network/access issue rather than a code regression.
Recommended Actions
- Ensure the CI runner can reach
(proxy.golang.org/redacted)(e.g., whitelist it, provide proper credentials, or use a reachable GOPROXY). - Cache or vendor critical Go modules so tests can run even if external downloads are blocked.
- Monitor for proxy HTTP 403s before running the test job so the failure surface happens earlier.
Prevention Strategies
Document the required outbound network access for Go module downloads and invest in a reproducible module cache to prevent transient proxy blocks from failing the entire suite.
AI Team Self-Improvement
Before running go test, verify that dependency downloads are allowed and update instructions to mention that proxy.golang.org must be reachable or that vendoring is required.
Historical Context
Similar failures have occurred when the Go proxy is blocked (every setup failed report shows Forbidden), so this looks like a recurring network restriction rather than a new code issue.
