Client Snippet

const { PrismaClient } = require("@prisma/client");
async function main() {
  const client = new PrismaClient();
  await client.$connect();
  const data = await client.table.findMany({
    where: { Id: "test" },
  });
  console.log(data);
  client.$disconnect();
}
main();

Schema

model table {
  Id     String  @id @default(dbgenerated("newid()")) @db.UniqueIdentifier
  Value  Int
}

Prisma cannot handle the SQL error when trying to match a string to UniqueIdentifier

Even better would be to have a proper uuid type so already you’d get an error in the client if your value is not a real guid.

That is what we ended up doing! We used https://github.com/NicolasDeveloper/guid-typescript to make sure, only valid GUIDs can be used.

I can reproduce the crash with above query and schema. Here is a packaged reproduction: https://github.com/harshit-test-org/prisma-issue-5869

We should look into this and fix it.
