Please do not copy node_modules inside Docker. It decreases your build time and prevents this kind of errors from happening.

Use a .dockerignore and add node_modules/ to it

Did anyone solve this problem?

[tobslob]

Adding node_modules to .dockerignore solved this.

docker is not detecting changes in the layers above "run npm ..." therefore it does not build the complete image. I solved it by exchanging run position with copy

I was having the same issue. Fixed by uninstalling bcrypt before building with docker, then adding bcrypt back to package.json. When you build with docker after adding bcrypt back to package.json, it should complete with no errors.
