Description
This issue was created by an agent analysing CI failures from the Next.js Deploy Suite (vinext
mainvs Next.jsv16.2.6, 2026-05-22).
Problem
Several suites consistently fail the deploy script with Custom deploy script failed: undefined (7) (react-version) or (1) (twoslash), with no test ever running. The exit codes suggest a missing toolchain dependency or unsupported config (e.g. multi-package react resolution / TypeScript compile failure).
Custom deploy script failed: undefined (7) — react-version
Custom deploy script failed: undefined (1) — twoslash
Estimated Impact
~7 test failures across the deploy suite.
Affected Test Suites
test/e2e/react-version/react-version.test.ts(5 failures)test/e2e/twoslash/index.test.ts(2 failures)
Recommendation
-
Reproduce first in vinext's own test suite. Run the deploy script directly against each fixture and capture the underlying stderr.
-
Triage the exit codes. Exit code 7 is commonly used by tools for
unmet dependency/not found— confirm which dependency or stage emits it. Exit code 1 needs the captured error message to triage. -
File targeted fixes. Both suites likely need separate root-cause fixes; this issue tracks the triage.
