Large decimals cause panick

[haydenbriese]

Bug description

Prisma crashes when trying to create large decimals, even when the field is configured for a far greater precision

thread 'tokio-runtime-worker' panicked at 'called `Option::unwrap()` on a `None` value', /Users/runner/.cargo/git/checkouts/quaint-9f01e008b9a89c14/479e08a/src/connector/postgres/conversion/decimal.rs:81:39

How to reproduce

1. Init db using schema
2. Execute example create

Expected behavior

I can create a decimal with a precision of 128

Prisma information

Schema

model Example {
  id     String  @id @default(uuid())
  number Decimal  @db.Decimal(128,0)
}

Call

await this.prisma.test.create({
  data: {
    number: "1" + "0".repeat(60), // 1e60
   },
});

@haydenbriese thanks for the report. May I close this given it is a duplicate of #7061

Though the error messages are the same, the two bugs appear to occur under different circumstances
This bug occurs for very large Decimals.
The other occurs for relatively small Decimals when they're marked with @id.

Whether they share the same underlying cause or not both cases should be tested.
I can document this case on the other ticket if you think that would be the best place for it

Ok that sounds good. We will triage and get to it as soon as possible. Thanks for reporting.

Hey,

This was fixed by prisma/quaint#379 and prisma/prisma-engines#2988, and should be available in the next release.

Closing now, thanks for reporting 🙏
