The logs show that the module is built correctly but I think you are
pulling in node_modules from the host. Check if node_modules is in your
dockerignore

Thanks a lot @agathver, I was actually ignoring the host's node_modules but I was uncorrectly mouting my volumes which were passing the node_modules to the container.

Thanks @recrsn! This solution solved my problem.
