Description

This issue was created by an agent analysing CI failures from the Next.js Deploy Suite (vinext main vs Next.js v16.2.6, 2026-05-22).

Problem

When serverExternalPackages (or equivalent) is configured, transitive dependencies resolve to the wrong version. Test expects depB: 4.17.21, 4.17.21, 5.0.0 but got depB: 3.10.1, 4.17.21, 5.0.0 — the first depB instance is wrongly resolved to depA's version.

Transitive externals resolution picks wrong package version

Estimated Impact

~1 test failures across the deploy suite.

Affected Test Suites

  • test/e2e/externals-transitive/externals-transitive.test.ts

Recommendation

  1. Reproduce first in vinext's own test suite. Add a fixture with depA -> depB@4 and root -> depB@3, mark depA as external, and assert each module sees the correct depB version.

  2. Preserve transitive version resolution. Externalising a package must not collapse nested copies of a transitive dep to a single version.
