Permission denied: '/media/data/fact_fw_data/91'

Hi all.
I have been trying to test the solution but I'm getting this error when I upload a file.

From the webserver, it shows upload successfully. However, If click on the analysis page, it shoes the file does not exist.

I followed this instructions:
$ docker pull ghcr.io/fkie-cad/fact-core-frontend:4.0.1
$ docker pull ghcr.io/fkie-cad/fact-core-backend:4.0.1
$ docker pull ghcr.io/fkie-cad/fact-core-scripts:4.0.1
$ ./start.py pull
$ ./start.py compose-env \
--firmware-file-storage-dir path_to_fw_data_dir
# Have a look if it looks right
$ eval $(./start.py compose-env --firmware-file-storage-dir path_to_fw_data_dir)
$ export FACT_DOCKER_POSTGRES_PASSWORD=mypassword
$ docker volume create fact_postgres_data
$ docker-compose up -d database
# Wait some seconds until the db is ready
$ ./start.py initialize-db \
--network fact_docker_fact-network
$ docker-compose up

The last command shos this warning:

fact-backend_1 | [2022-11-17 04:09:22][start_fact_backend][WARNING]: Could not change permissions of docker-mount-base-dir. Ignoring.

My Linux system is
Linux 5.15.0-53-generic #59-Ubuntu SMP Mon Oct 17 18:53:30 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux.

I appreciate any indication/help

Thank you.

Start with the compose-env command, the configured firmware storage directory, and the docker-compose setup. Reproduce the upload while checking the backend warning about changing permissions and the traces in fail_safe_file_operations.py, unpacking_scheduler.py, unpack.py, and fsorganizer.py. Done means uploaded files can be unpacked and opened from the analysis page without permission or missing-file errors.
