Not all files present in final build when using `context`

[X] There are no open or closed issues that are related to my problem

Description

The build and push step seems to ignore some files that were created beforehand. I have a step that runs an npm run build that creates some js files, but those files do not seem to be in the resulting image.

I've added a debug step that runs an ls to check if the files are created I use the context: . option .dockerignore doesn't seem to be the problem

Expected behaviour

That the final docker image contains the newly created files

Actual behaviour

Files are missing

Additional info

I've tried multiple other options before opening this issue. Weirdly enough the node_modules folder created with run: npm install is present in the final image so I'm not sure where the issue is coming from

docker / build-push-action
