## Description

Polyglot SDK Validation: TypeScript SDK Validation (Node 22.x) job fails with exit code 1, unrelated to PR-changed files; job logs unavailable for detailed diagnosis

**Type**: infra-failure

## Occurrences

| Date | Build | Job | PR |
|------|-------|-----|----|
| 2026-09-03 | [33811778450](https://github.com/microsoft/aspire/actions/runs/33811778450) | Tests / No-package tests (regular, Aspire.Azure.Npgsql.EntityFrameworkCore.PostgreSQL.Tests...) / Azure.Npgsql.EntityFrameworkCore.PostgreSQL (windows-latest) | #19918 |

Start with build 33811778450 and the failing Azure.Npgsql.EntityFrameworkCore.PostgreSQL job on windows-latest, then compare it with PR #19918. Investigate why the TypeScript SDK Validation job reports exit code 1 despite unavailable logs, including the downstream Check validation results failure. Done means the failure cause is identified and the affected validation job completes successfully.
