Unable to deploy a python application from az cli

We have a problem deploying a python application to App service using the Az CLI. Do you have an idea of the problem source ?

Here is the command we use. We execute it on an ubuntu VM.az webapp up -n $WEB_APP_NAME -l "westeurope" -g $RESOURCE_GROUP_NAME --sku B1

Here is the error we have. We don't get it :

Zip deployment failed. {'id': '200a84e1e024461ca2ef18edd8c3f607', 'status': 3, 'status_text': '', 'author_email': 'N/A', 'author': 'N/A', 'deployer': 'Push-Deployer', 'message': 'Created via a push deployment', 'progress': '', 'received_time': '2021-06-22T15:49:57.8395052Z', 'start_time': '2021-06-22T15:49:59.5399261Z', 'end_time': '2021-06-22T15:50:13.4118115Z', 'last_success_end_time': None, 'complete': True, 'active': False, 'is_temp': False, 'is_readonly': True, 'url': 'https://test-surveillance-api-2.scm.azurewebsites.net/api/deployments/latest', 'log_url': 'https://test-surveillance-api-2.scm.azurewebsites.net/api/deployments/latest/log', 'site_name': 'test-surveillance-api-2'}.
