I am creating a flask app that can upload files to my azure blob. When I test the code locally on my python virtualenv, the app works perfectly. When I create a docker container and push the image to Azure App services, container log shows below error:

GAME OVER *** I have tried multiple solutions mentioned on Github issues and other similar stackoverflow queries. The usual suggestions were to install azure-storage < 0.36, install azure==0.11.1 etc but none of them have solved my problem. https://github.com/Microsoft/AzureNotebooks/issues/460 https://github.com/Azure/azure-sdk-for-python/issues/3623
#azure==0.11.1 #azure==2.0.0 click==6.7 Flask==0.12.2 itsdangerous==0.24 Jinja2==2.10 MarkupSafe==1.0 Werkzeug==0.14.1 #azure-common==1.1.3 #azure-nspkg==1.0.0 azure-storage==0.31.0 futures==3.0.5 python-dateutil==2.5.3 requests>=2.20.0 six==1.10.0 Can anyone help me understand the cause of this issue.
Edit: Adding my code for as requested in one of the comments:
