ServiceBus trigger in an Python function- clientRetryOptions setting of host.json does not work

[sdg002]

Hello Team, I have an Azure Service Bus queue trigger function and I am trying to implement exponential back by following the Microsoft guidance here.

What is the function implementation language?

Python

I have modified Host.json as below

I have specified extensionBundle as below

When I debug the Azure function, I notice that the function retries, however it does not honor the exponential back-off setting. All retries are sequential and almost within the same second

Tried installing extensions

I tried the following command with an presumption that I need to update the extension version

func extensions install --package Microsoft.Azure.WebJobs.Extensions.ServiceBus --version 5

But, this gave the message No action performed. Extension bundle is configured in C:\Users\myusername\MyTrials\any-python\AzureFuncTimerRetry\src\host.json

Relevant links

• How does clientRetryOptions work in relation to Retry Policies?

• The retry policy support in the runtime for triggers other than Timer and Event Hubs is being removed

Can somebody from Microsoft please clarfiy?

Thanks.

@sdg002 You can use these settings to override host.json settings in your Function app. https://dev.to/massimobonanni/azure-functions-tips-override-the-hostjson-settings-21mi This worked for us
