I am happy to share our schema / migrations through a private channel.

I'm not clear this is a bug. If I understand, the user is trying to cast to a union of types, which I don't think should be possible. Maybe someone else can have a look too?

@elprans has a copy of my dbschema folder. You should be able to reproduce this by adding a variant to the ContactBookEntrySource type.

e.g. start with

        required from_source -> KnownFromVisitingSocialEvent | LinkedinUpload;

and change to

        required from_source -> KnownFromVisitingSocialEvent | LinkedinUpload | GoogleCalendar::Calendar;

I have since updated the schema but IIRC this is how I was able to produce the problem.
