Unused '@ts-expect-error' directive on npm build

[SirLouen]

Description

When building lately (npm run build), I'm getting these errors

packages/core-data/src/utils/crdt-blocks.ts:13:1 - error TS2578: Unused '@ts-expect-error' directive.

13 // @ts-expect-error No exported types.
   ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

packages/core-data/src/utils/crdt.ts:9:1 - error TS2578: Unused '@ts-expect-error' directive.

9 // @ts-expect-error No exported types.

Wondering if this has already been reported. I've been searching, but I could not find anything.

Step-by-step reproduction instructions

Do a regular build: npm run build

I can't reproduce it. Did you try running npm run clean:package-types before npm run build?

I solved it yesterday, but to be sincere, I'm not sure if I actually sorted this with clean:package-types
It's weird because theoretically there should be a message that suggests this, but it wasn't appearing.

I will monitor if this pops back in the future.

@manzoorwanijk It's back 😲

$ npm run clean:package-types

> gutenberg@22.0.0 clean:package-types
> tsc --build --clean && rimraf --glob "./packages/*/build-types"

$ npm run dev

> gutenberg@22.0.0 dev
> node ./bin/dev.mjs

Found 2 errors.


❌ TypeScript compilation failed. Try cleaning up first: `npm run clean:package-types`

❌ Dev build failed: TypeScript compilation failed

Yesterday in the patch-testing-scrub some members also got this error. It seems to be generalized. We are using Windows under WSL2 with Ubuntu.

Tested in node 22.16 and 20.19.5, npm 11.5.2 and 11.6.2

Also with a clean clone from scratch

I also have this trouble. I have to apply this patch to get the build to work:

It seems the problem is to locate gutenberg project as a plugin of a wordpress-develop project
