Basing this off of my current setup.

Try creating the following folder structure:

• foo/
  • index.ts
• bar/
  • index.ts

Contents in foo/index.ts:

export interface Thing {
}

Contents in bar/index.ts:

export let thing: Thing;

Try using the appropriate code action to import Thing. The generated code is currently:

import { Thing } from "../foo/index"; 

The fix is correct, however, most people don't include index as part of their path when importing a module. I'd argue that TypeScript shouldn't either.
