Unable to load metadata for function - KEDA Function running on AKS.

[gaikwadsantosh]

We are deploying Azure Function in AKS using KEDA.
As per design whenever a message arrived in a service bus, KEDA function will trigger and consume the message.

However intermittently I am getting error "Unable to load metadata for function" and message in service bus is not even put in dead letter queue.

very similar to issue reported here Azure/azure-functions-host#7238

I am running this C# function in AKS, and utilization of AKS resources is well below 50% when this error occurs.

However one important observation we have is, code works well is with version 5.1.0 of Microsoft.Azure.WebJobs.Extensions.ServiceBus and same code stops working with newer version 5.13.5

kindly suggest some solution.

I had already created ticket in Azure, however they suggested me to open ticket with GitHub

[gaikwadsantosh]

could it be a problem because of having long running (heavy) code in function?

May I know why functions are running as containers on AKS?
