Error with the build in the Deploy process

I try to deploy the new version of invoice_template in staging environment and the process raises the next error:

"PermissionError: [Errno 13] Permission denied: /home/opencell/postgresql/data"

Context:

TASK [deploy : Ensure our docker-compose definition is up and rebuild opencell image.] ***************
