Issue seems to be related to NativeModules returning an empty object. Trying to reference to NativeModules.Prisma which will give null.
Output: NativeModules {}

Thank you for reporting this Nabil.

To help me narrow this down, can you confirm that you are doing the following:

1. Adding the Expo plugin "plugins": ["@prisma/react-native"] and running prebuild npx expo prebuild --clean
2. setting previewFeatures = ["reactNative"] in the schema as per the readme
3. generate initial migrations and a database if it doesn't exist: npx prisma@latest migrate dev
4. generating the client: npx prisma@latest generate
5. running prebuild to activate the Expo plugin

Prisma relies on a native module, so Expo Go isn't supported at the moment.

I'm facing same issue. I've tried all steps above, but prisma failed to initialize

Thanks @Skr1pt1k. Now, I'm wondering what's special about your setup. Would you be able to invite me to a repo or create a minimal reproduction I can debug?

I was able to recreate this issue and even solve it I don't know why but when you define the sceham.prisma in some ./**/ directory the prisma is not able to initialize or sometimes access the database same goes for many other issues created on this repo. I was even able to solve it by creating the schema.prisma in the ROOT_DIR of the project which then allows PrismaClient to work perfectly as expected. Other issues which I faced was

1. main.Table not found due to the reason PrismaClient cannot access the DB
2. property __PrismaProxy doesnot exist
3. @prisma/react-native failed to initialize, js-engine hermes

Also having this issue. Interesting is that I don't have the issue with the example project https://github.com/sorenbs/budget-buddy-expo. I tried installing the same version of all prisma dependencies in the package.json from that project and mirroring configuration as closely as possible, but I still can't get rid of the error in my own project...

Edit: also working in a new project created with create-expo-app

I figuerd out for me the problem was

1. Do not run it under expo go but on device via npx expo run:android --device (substitute android for ios if needed) and do not connect via the QR code or the app
2. Make sure to have the prisma file in the root directory
3. ONLY use it with the extended client, never use the normal client without extension. Working for me was the following code I borrowed from https://github.com/sorenbs/budget-buddy-expo
   Just use the exported prisma client and it worked

import '@prisma/client/react-native';
import { PrismaClient } from '@prisma/client/react-native';
import { reactiveHooksExtension } from "@prisma/react-native";

const basePrisma = new PrismaClient()
basePrisma.$applyPendingMigrations();
export const prisma = basePrisma.$extends(reactiveHooksExtension());

PS: Make sure to run npx prisma generate
npx expo prebuild --clean before all

EDIT: I still receive the error in the console sometimes when reloading, however afterward it initializes fine, applies the migrations without problems and runs all queries. Maybe try if it works for you too

What version of prisma, @prisma/client and @prisma/react-native are you using

The issue also persists for me, even when I run the base project from @sorenbs : https://github.com/sorenbs/budget-buddy-expo with all the prerequisites steps mentioned above. Any potential fixes?
