[SOLVED] MongoDB Atlas + prisma + nextjs error: Error validating datasource `db`: the URL must start with the protocol `mongo`


This Content is from Stack Overflow. Question asked by user3226932

can’t connect to mongodb server when using env var in mongodb + prisma + nextjs application. getting this error error: Error validating datasource db: the URL must start with the protocol mongo.

datasource db {
  provider = "mongodb"
  url      = env("DATABASE_URL")

.env: DATABASE_URL=mongodb+srv://username:password@somemongodbserver/mydb?retryWrites=true&w=majority

.env.local: DATABASE_URL=mongodb+srv://username:password@somemongodbserver/mydb?retryWrites=true&w=majority

Also tried putting this in next.config.js

const nextConfig = {
  reactStrictMode: true,
  swcMinify: true,
  env: {


turns out I already I had DATABASE_URL env var set locally for Postgres and it was being used, changing the env var name in the nextjs app fixed the issue
