[api-extractor] Some relative path imports of local files are not resolved anymore since 7.49.0 #5126
Description
Summary
I am using vite-plugin-dts with rollupTypes: true to create a rollup of the type declarations. After upgrading, I am experiencing some errors. After narrowing down the problem, it seems like this is a regression that was introduced with api-extractor 7.49.0. With 7.48.1 the problem does not occur anymore.
With api-extractor 7.49.0, the resulting bundle contains imports like this:
import { CRUValidatorForDeclaration as CRUValidatorForDeclaration_2 } from './cru.js';The file cru.js is part of my package and its contents should be embedded in the bundle, which worked correctly with 7.48.1. The path ./cru.js does not lead anywhere, since that file does not exist in the output folder where the bundle is saved. The relative path is simply preserved from how it is specified in the source file.
Repro steps
I have copied the relevant package to this repository. To create a build, run yarn install and then yarn build. This will generate the bundle as dist/facilmap-types.d.ts.
The repository uses api-extractor 7.48.1, so the generated bundle does not have the problem described. To reproduce the problem, change the api-extractor resolution in package.json to 7.49.0 and run yarn install and yarn build again.
To investigate the declaration files that the bundle is generated from, set rollupTypes to false in vite.config.ts and run yarn build. This will generate the raw declaration files under dist.
