Import autosuggestion doesn't work (default export error)

[wclr]

TypeScript Version: 4.0.3

Import autosuggestion stoped work in a project. Doesn't work with the 4.1 dev too.

This is a full trace log from output
https://gist.github.com/whitecolor/19e6ded72a8eb90a874beff468a5b552

There some errors Error: Debug Failure. Alias targets of default exports must have a parent don't know if it relates.

It does look like that’s related, but I would need a full working repro to be able to do anything here, since most auto imports do in fact work in 4.0.3 😄

I have debugged it.

It was due to this module, added recently in the project:

import { LocalStorage } from 'node-localstorage'

if (typeof localStorage === 'undefined' || localStorage === null) {
  console.log('localStorage')
  const localStorage = (global.localStorage = new LocalStorage('./.tmp/scratch'))
  localStorage.clear()
}

export default global.localStorage // this line cauzed it.

So when I removed the line:

export default global.localStorage

It started to work, so something went wrong with default export with global, so it seems the error in the log relates because there was no one after the fix.

Great, thanks for narrowing it down!

@whitecolor I actually still can’t reproduce this. Can you please provide a full repro? I.e., tsconfig.json, package.json, and all source files. A link to a repository would be great.
