Azure Function App Server Error due to FUNCTIONS_WORKER_PROCESS_COUNT setting

Question

Hello,

I am using consumption plan of azure function python 3.11. I deployed a durable function which uses python programming model v1 from my vs code. THis is how the host.json looks like...

The function app deploys fine, but I want concurrency and when I add FUNCTIONS_WORKER_PROCESS_COUNT setting with a value of 10 I get server error and logs also do not show anything apart from 'Connected!'

When I remove the FUNCTIONS_WORKER_PROCESS_COUNT settings the app starts working. Please tell me how to resolve this to achieve working of parrallel tasks. THanks
