Can not be used when multiple nested aliases are involved

Bug report
When I use it in a monorepo project, I can not export the type correctly, and usually the result is a null value
Input code

export { debounce, get, merge, mergeWith, set } from 'lodash-es';

this exportElementSymbol is undefined, and throw an error.

@Gggpound what error are you getting in your codebase? I can reproduce an error Error: Something went wrong - a symbol debounce for top-level identifier debounce cannot be renamed but it seems it is not what you're getting?

@Gggpound any news?

Hi, I’m encountering similar issue described here, and I’d like to provide more details that might help reproduce and diagnose the problem. Apologize for using AI to generate this comment, since my English is not very good.

Project Structure & Context

I'm using dts-bundle-generator in a monorepo (using pnpm workspaces), and my issue occurs when trying to generate a bundled declaration file from a package (A) that depends on another internal workspace package (B).

Key Info

1. Package A depends on Package B via workspace reference ("@myorg/pkg-b": "workspace:*").
2. Each package uses an index.ts as the main entry point, and uses the pattern:

   export * from './module-a';
   export * from './module-b';

3. My codebase includes some JSX/TSX files using React.
4. I have set followSymlinks to false.
5. During dts-bundle-generator execution, I get a crash with the following stack trace:
