This is caused by ts-node recent update. see https://github.com/TypeStrong/ts-node/pull/1771 as reported by https://github.com/TypeStrong/ts-node/issues/1790. Downgrade ts-node to 10.8.0 result the issue for me.

[NikolayMakhonin]

Yes, it working with ts-node@10.8.0, but not working with ts-node@10.8.1

I just confirmed the fix in ts-node 10.8.2 resolves the issue for me.
