After some debugging, it seems that the “Pre User Registration” flow is completely ignored for passwordless singnups.
The issue was the same for the Hooks. I opened a topic here 3 years ago (Pre Registration hook not running when creating a Passwordless user)) but it was never implemented on the Hooks. I’d hope that the new Actions would fix this but it does not seem to be the case
I also found this FAQ Cannot set AppMetadata or UserMetaData in Passwordless flow with Pre-registration Action / Hook which says
With Passwordless connections, it is not supported to use the pre-registration Action because it works differently than with the other connection types.
but the docs themselves say:
The Pre User Registration Flow runs before a user is added to a Database or Passwordless Connection.
