I experience the same issue.
additionally if i try to run the expose method in the worker script without importing it in the main thread, i get this error:

node:internal/event_target:1010
  process.nextTick(() => { throw err; });

Error: expose() called in the master thread.

I experience the same issue with cjs if i put "type": "module" in my package.json

it is impossible for me to remove "type": "module" from my package.json because a plugin in my build chain relies on it so i am at the moment unable to use this package.

This is fixed in master branch by #419
But we haven't see a new release includes this fix yet. What time is the 1.7.1 release planed to?
