Default Value of False Fails Contract Validation

[dylan-cancelliere]

Package and version

@prisma-next/postgres@0.14.0

What happened?

Having a default value of a boolean column of false generates an incorrect contract artifcat (via prisma-next contract emit), which subsequently fails validation (via prisma-next migration plan).

What did you expect to happen?

it seems like in the generated contract.json there's a missing "value" field when comparing to the output with a default value of true (which does validate successfully).

Incorrect output, editied for clarity:

"foo": {
  "columns": {
    "bar": {
      "default": {
        "kind": "literal"
      },
    }
  },
},

Correct output:

"foo": {
  "columns": {
    "bar": {
      "default": {
        "kind": "literal",
        "value": true    // Here
      },
    }
  },
}

Minimal reproduction

contract.prisma:

model Foo {
  bar Boolean @default(false)
}

Additional context

Encountered this my first time trying Prisma, apologies if it's dumb user error 😅
