PrismaClientValidationError: Unknown argument

PrismaClientValidationError:
Invalid `db.user.findMany()` invocation:

{
  where: {
    emial: "[email protected]",
    ~~~~~
  }
}

Unknown argument `emial`. Did you mean `email`? Available options are marked with ?.

What it means

The query uses a field or option the generated client doesn't know. Prisma checks every query against your schema before sending it.

Common causes

• The agent guessed a field name (userId vs ownerId, createdAt vs created_at)
• The field exists in schema.prisma but the client wasn't regenerated
• A relation filter written like a scalar: where: { user: id } instead of where: { userId: id }

How to fix it

1. Use the name Prisma suggests after "Did you mean"
2. If the field is new, run npx prisma generate
3. Let TypeScript check queries: don't type db or the query args as any

Prompt for Cursor or Claude Code

Prisma throws a PrismaClientValidationError (Unknown argument). Read prisma/schema.prisma, then fix the query to use the real field names. If the field was just added, run prisma generate. Don't cast to any to silence it.
