I have found that callable functions from javascript web clients are broken with SDK version 7.21.1. If you downgrade to 7.21.0, it should work OK. The latest 7.22.0 still seems broken.

This has been filed on GitHub if you want to track it.

Update Oct 5, 2020: Apparently this has been fixed in 7.22.1.
