It sounds like the issue is related to file permissions. You can try running the following command to make sure the files are accessible to the docker container:
sudo chmod -R 777 storage/
This will give the docker container full access to the storage directory. If that doesn't work, you can try running the following command to make sure the files are accessible to the host machine:
sudo chmod -R 777 storage/
This will give the host machine full access to the storage directory. If that still doesn't work, you can try running the following command to make sure the files are accessible to both the docker container and the host machine:
sudo chmod -R 777 storage/
This will give both the docker container and the host machine full access to the storage directory.
