Validator Error Message is Not Shown

[danielyogel]

Steps to reproduce:

1. create a table of union of objects https://docs.convex.dev/database/schemas#unions.
2. update a row using .patch(), add extra fields like the default _id and _creationTime
3. transaction fails, message includes only the "value" and "validator", and when testing them locally in a script - the error message shown is still wrong.

Thanks!
