maxDequeueCount config setting not working for Azure Function

Question

I have an an Azure Function which I want to fail and sent to the poison queue if it errors once or twice. I've set the maxDequeueCount property in my host.json file to 1, but it still retries 5 times. Based on all the doco I've read this seems to be correct. Does anyone have any suggestions? Below is a sample of my hosts.json.

{
  "version": "2.0",
  "logging": {
    "fileLoggingMode": "debugOnly",
    "logLevel": {
      // For all functions
      "Function": "Trace",
      // Default settings, e.g. for host
      "default": "Trace"
    },
    "extensions": {
      "queues": {
        "visibilityTimeout": "00:01:00",
        "maxDequeueCount": 1
      }
    }
  }
}

Were you using storage queue trigger or service bus queue trigger? — Tony Ju, May 16 '20 at 14:45

For storage queue trigger, to change frequency of the retry, we just need to change the value of maxDequeueCount. Please go to azure portal to check the host.json file.

{
  "version": "2.0",
  "extensionBundle": {
    "id": "Microsoft.Azure.Functions.ExtensionBundle",
    "version": "[1.*, 2.0.0)"
  },
  "extensions": {
    "queues": {
      "maxDequeueCount": 1
    }
  }
}

If the feature still doesn't work after restarting the function, I afraid that you need to raise a support ticket on azure portal, they will check the backend logs for you.
