I got this in my schema:

  id               BigInt          @id @default(autoincrement())

I think this is an issue with prisma itself and nothing to do with adminjs. prisma/studio#816

facing the same issue

ok, So I fixed it by patching the bigint prototype
BigInt.prototype.toJSON = function () { const int = Number.parseInt(this.toString()) return int ?? this.toString() }
