Error: @prisma/client did not initialize yet. Please run "prisma generate" and try to import it again.

I don't know why the server returns this error beacuse I have already configured Prisma and Prisma client and also I have already run the command

npx prisma generate

npx prisma generate

. I have attached my

schema.prisma

schema.prisma

file and

package.json

package.json

schema.prisma

You selected the carefully hand-crafted route. A dev artisan will respond soon. Meanwhile, the #ask-ai channel awaits if you're curious!

I’m unable to open your schema on mobile, but are you using a custom output path? If so, you should import from that and not from @prisma/client

ahduaehfkdaOP•4mo ago

Thanks for your reply but the output path is the same written by Prisma Client and is the same written on the documentation.

jonfanz•4mo ago

Yes, I meant in your code, not in the Schema. You most likely have this line somewhere:

import { PrismaClient } from '@prisma/client'

import { PrismaClient } from '@prisma/client'

I have created this simple server, but when I run it it still returns the same error.

jonfanz•4mo ago

Yup, change the first line of utils/prismaClient.ts. it should have the relative path to your generated client, NOT @prisma/client.

ahduaehfkdaOP•4mo ago

Thaks bro for helping me, now it works and sorry for my oversight on utils/prismaClient.ts.

jonfanz•4mo ago

No problem! Going to mark this as resolved
