Function app return 404 on first call after long time of idle. #7522
Description
I have a simple function that just connect to CosmosDB and return value. My code is written in python and I am using Linux consumption plan.
Region: Southeast Asia.
I don't have application insight enable so that I have no other information. If you need my function name, I will send it to you by personal message. Or please teach me other way to get the Function ID without application insight.
Steps to reproduce the issue:
- Let Azure Functions be idle for a long time.
- Call a function.
Actual behavior: Azure Function return 404 on the first calls, but the following calls are successful.
Expected behavior: Azure Function should hold the connection, waiting for the functions to be prepared. After that it should return the result.
Other note: Even I called the function 7 times (2 failed and 5 successful), the Azure Function metric just shows that I called it 5 times.
Actually I think the problem is similar to #7451 , but balag0 at the page told me to make a separate page, so that I made it here.
