Descripción

bug
Describe the bug

Currently the release of loopback-next modules is blocked by the error when running the command npm run tsdocs as part of the release process.

Here is the error:

> @loopback/typeorm
Analysis will use the bundled TypeScript version 5.2.2

I've tried a few things but still wasn't able to identify the problem:

  1. force showVerboseMessages to be true in https://github.com/loopbackio/loopback-next/blob/master/packages/tsdocs/src/monorepo-api-extractor.ts#L258C5-L258C24 -> no effect
  2. added showDiagnostics: true, before the line specified above -> it printed more info but it didn't mention where the error could be coming from.
  3. When searching for similar errors, someone suggested (I lost the location where I saw that) to delete the folder node_modules/@microsoft/api-extractor/node_modules/typescript. But it didn't help either.

Since it's blocking the release of LB4 modules, we could possibly remove the api-extractor scripts. We would not have the latest API docs but at least we have the modules published while we're figuring this out.

@loopbackio/loopback-maintainers, thoughts?
