I encountered the Prisma error "The 'path' argument must be of string. Received undefined". A complete reinstallation of packages resolved the issue: bashCopy# Remove existing packages npm uninstall @prisma/client prisma

Reinstall packages

npm install prisma --save-dev npm install @prisma/client

Generate Prisma client

npx prisma generate --schema=./prisma/schema.prisma # If schema is in custom location

OR

npx prisma generate # If you're in directory containing prisma/
