Fixes runtime error where Prisma Client could not locate the Query Engine:
"libquery_engine-debian-openssl-1.1.x.so.node" not found
Root cause:
- Next.js standalone output does not include Prisma Query Engine binaries
- The .prisma folder in node_modules contains the required binary files
Solution:
- Copy node_modules/.prisma folder in Docker runner stage
- This includes libquery_engine-debian-openssl-1.1.x.so.node
- Prisma Client can now find and load the Query Engine at runtime
Tested:
✓ Docker build successful
✓ Container starts without Prisma errors
✓ Application ready in 40ms
Changes:
- keep-notes/Dockerfile: Add COPY for node_modules/.prisma folder
