[6.x] WebAssembly.instantiate(): Import #0 "./query_compiler_bg.js": module is not an object or function] #26880
Description
Bug description
Nitro + Prisma 6.6.0 + D1 does not work
Severity
🚨 Critical: Data loss, app crash, security issue
Reproduction
https://github.com/medz/nitro-prisma-6.6
Expected vs. Actual Behavior
Expected behavior: WASM modules can be parsed normally
Frequency
Consistently reproducible
Does this occur in development or production?
Only in development (e.g., CLI tools, migrations, Prisma Studio)
Is this a regression?
Prisma: 6.6.0
Nitro: 2.11.9
wrangler: 4.10.0
Workaround
Prisma Schema & Queries
datasource db {
provider = "sqlite"
url = env("DATABASE_URL")
}
generator client {
provider = "prisma-client"
output = "./client/"
previewFeatures = ["driverAdapters"]
runtime = "cloudflare"
}
model Result {
id String @id @default(uuid(7))
createdAt DateTime @default(now())
}
import { PrismaD1 } from "@prisma/adapter-d1";
import { PrismaClient } from "~/prisma/client";
export default defineEventHandler((event) => {
const adapter = new PrismaD1(event.context.cloudflare.env.DB as any);
const client = new PrismaClient({ adapter });
