[object Object] is not valid JSON

[dan-coman]

I think there is a double JSON.parse both done by prisma and the adapter.
Using a turborepo with next v16 and Turbopack.

Packages:

"@prisma/client": "6.17.0"
"prisma": "6.17.0",
"@tidbcloud/prisma-adapter": "^6.17.0",
 "@tidbcloud/serverless": "^0.2.0",

Client config:

generator client {
  provider        = "prisma-client"
  output          = "../generated/client"
  engineType      = "client"
}

Database package:

import { PrismaTiDBCloud } from '@tidbcloud/prisma-adapter';
import { PrismaClient } from './generated/client/client';

export * from './generated/client/browser';
export type { Booking, Customer, Payment } from './generated/client/client';
export * from './generated/client/enums';

const globalForPrisma = globalThis as { prisma?: PrismaClient };

const adapter = new PrismaTiDBCloud({ url: `${process.env.DATABASE_URL}` }) as any;

export const prisma =
  globalForPrisma.prisma ||
  new PrismaClient({
    log: process.env.NODE_ENV === 'development' ? ['query', 'error', 'warn'] : ['error'],
    adapter,
  });

if (process.env.NODE_ENV !== 'production') globalForPrisma.prisma = prisma;

Query usage: ("accomodation" is a Json type field)

await prisma.booking.findFirst({
    select: { accomodation: true },
    where: { publicId: '_oUbnAZN2McwE_EJuXbOL' },
  });

Error:

 prisma:error "[object Object]" is not valid JSON
