is there a limitation around having multiple unique fields on a schema? it was working fine with us with id, email, but we're adding a facebook-user-id to the mix, which is also unique. and having "weird" error

"Cannot query field 'facebookUserId' on type 'User'. (line 4, column 5):\n    facebookUserId\n    ^",

Is that the end of the error?

yeah, very unsure about it all, however, got to get it working on my own environment (that was on my colleague's computer), it works, now -- clueless

And was that error from a dev playground query?

sounds like an outdated schema.graphql or prisma.graphql file
