Error: @prisma/client did not initialize yet. Please run "prisma generate"

What causes this error

Prisma Client is code-generated from your `schema.prisma` file into `node_modules/.prisma/client`. Since that's inside `node_modules`, it's gitignored by default — so a fresh clone, a fresh `npm install`, or a schema change without regenerating will leave you with an outdated or missing client.

The Fix

npx prisma generate

Add it as a `postinstall` script so it happens automatically:

// package.json
"scripts": {
  "postinstall": "prisma generate"
}

Common causes / variations

• Cloning the repo fresh and running `npm install` without a postinstall hook
• Editing `schema.prisma` and forgetting to regenerate before restarting the dev server
• Deploying to a platform that caches `node_modules` and skips a clean install
