Why the starting command for my Strapi project fails within the Docker environment

Question

I am trying to dockerize my strapi application, but the entrypoint command fails with:

error bootstrap function in plugin "documentation" failed
error TypeError: Cannot read property 'attributes' of undefined

The project is starting without any issues on my mac. I've tried the solution from here that implies removing the node_modules files and installing again, but without luck. I've also tried to start from different strapi images (with node-14,alphine etc). Do you guys have any idea about how I could solve this error or what's the cause of it? I am pretty new with the docker, maybe it's something wrong with the volumes? The other services from my docker-compose are working just fine.

This is my docker-compose file

    version: "3.9"
