Browser-imported 'Prisma.DBNull' create an empty object #29257
Description
Bug description
Using 'prisma-client' (Prisma 7.4.x), using 'Prisma.DBNull' from the browser import results in an empty object {} being persisted into a nullable Json field.
Severity
🔹 Minor: Unexpected behavior, but does not block development
Reproduction
import { Prisma as PrismaClient } from "./generated/prisma/client";
import { Prisma as PrismaBrowser } from "./generated/prisma/browser";
// This works as expected:
async function createClientExample() {
"use server";
await prisma.example.create({
data: {
name: `Client Example`,
json: PrismaClient.DbNull,
},
});
}
// This inserts an empty object {} instead of NULL
async function createBrowserExample() {
"use server";
await prisma.example.create({
data: {
name: `Browser Example`,
json: PrismaBrowser.DbNull,
},
});
}Example repo: https://github.com/JoGoFo-/prisma-dbnull-issue
Expected vs. Actual Behavior
Expected:
Json record is set to NULL
Actual:
Json record is set to {}
Frequency
Consistently reproducible
Does this occur in development or production?
Both development and production
Is this a regression?
Yes, this worked correctly in Prisma 6.x with 'prisma-client-js'
Workaround
Import client version of Prisma instead (server-side only)
