fix: resolve CI TypeScript build errors and ESLint violations in PostGraphile v5 integration by Copilot · Pull Request #9342 · ardatan/graphql-mesh

Copilot · 2026-03-19T21:27:32Z

Investigate CI failures (TS2307 + TS2322 in three PostGraphile packages)
Fix root cause: tsconfig.build.json uses moduleResolution: node which cannot resolve package exports subpath entries (postgraphile/presets/amber, @dataplan/pg/adaptors/pg)
Add ambient module declarations in declarations.d.ts as fallbacks for moduleResolution: node (ignored when moduleResolution: bundler resolves via exports map)
Add declare namespace GraphileConfig { interface PgAdaptors } augmentation so pgServices element type is never never[] (fixes TypeScript 6's stricter any-to-never check)

Original prompt

This section details on the original issue you should resolve

<issue_title>Update Postgraphile to the latest</issue_title>
<issue_description>Currently the postgraphile version that Mesh handler uses has an older version of GraphQL js which leads conflicts when you use the newer version.
