How to raise node.js + mysql via docker-compose?

Question

Node.js

What is the problem ?
When running docker-compose up --build gives
this error, I understand that the problem is in the COPY command, but I do not understand what exactly is wrong.

Building app

Build comes from the current directory. The file with the package in the Dockerfile is relative to the src directory
This is the error
Most likely - the easiest way to solve it is to add it to context: ./srcthe docker compose
And I highly recommend that you familiarize yourself with the concept of docker context
