🔹 1. Check .env File

Ensure that your .env file contains the correct DATABASE_URL:

DATABASE_URL="mongodb+srv://username:password@cluster.mongodb.net/dbname?retryWrites=true&w=majority"

• Ensure there are no spaces before or after = in DATABASE_URL.
• Replace:
  • username → Your MongoDB username
  • password → Your MongoDB password
  • cluster.mongodb.net → Your MongoDB Atlas cluster
  • dbname → The database name you want to use

🔹 2. Ensure .env is Loaded Properly

Run:

echo $DATABASE_URL

or, if using Windows:

echo %DATABASE_URL%

• If empty, Prisma is not loading your .env file.
• Try manually setting it before running Prisma commands:

export DATABASE_URL="mongodb+srv://username:password@cluster.mongodb.net/dbname?retryWrites=true&w=majority"
npx prisma db push

For Windows PowerShell:

$env:DATABASE_URL="mongodb+srv://username:password@cluster.mongodb.net/dbname?retryWrites=true&w=majority"
npx prisma db push

🔹 3. Manually Load .env File

If Prisma is not picking up the .env file, explicitly load it using dotenv-cli:

1️⃣ Install dotenv-cli:

npm install -g dotenv-cli

2️⃣ Run Prisma commands with .env:

dotenv -e .env -- npx prisma db push

🔹 4. Check prisma/schema.prisma

Ensure your Prisma schema is correctly set up:

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

🔹 5. Delete node_modules and .prisma Cache

Try clearing cache and reinstalling dependencies:

rm -rf node_modules/.prisma
rm -rf node_modules
npm install
npx prisma generate
npx prisma db push

🔹 6. Use --schema Flag

Explicitly specify the schema file:

npx prisma db push --schema=prisma/schema.prisma

🔹 7. Ensure MongoDB Atlas is Accessible

If using MongoDB Atlas:

• Whitelist your IP in MongoDB Atlas Network Access settings.
• Use SRV connection string (mongodb+srv://...) for cloud MongoDB.

✅ Final Check

Try running:

npx prisma validate

This checks if Prisma can read the schema.

Then retry:

npx prisma db push

If the issue persists, let me know what you get from echo $DATABASE_URL and npx prisma validate. 🚀
