Question

I'm trying to use @QueueTrigger for testing my Azure Function locally, but while triggering it from

http://localhost:8080/admin/functions/my-queue-trigger

I'm getting this error:

[2022-07-31T15:39:45.203Z] System.Private.CoreLib: Exception while executing function: Functions.my-queue-trigger. Microsoft.Azure.WebJobs.Host: Exception binding parameter 'request'. Microsoft.Azure.WebJobs.Extensions.Storage: Unable to convert trigger to IStorageQueueMessage.

Code:

@FunctionName("my-queue-trigger")
    public void run(
            @QueueTrigger(
                    name = "request",
                    queueName = "my-queue",
                    connection = "storage-conn-string"
            ) String request,
            final ExecutionContext context) {
        // logic
    }

I'm setting storage-conn-string in local.settings.json file as well. Could you please help where I'm going wrong?

I was facing a similar issue, for me I used some JSON in my POST other than

{
    "input": <your data here>
}

I was using this

{
    "test": "test"
}

which raised the error. Maybe this is of any help to you.

@jo2 I used request json as

{}

This worked for timer-trigger but not for queue trigger.

[jo2]

That might be the problem. queue trigger expects input as the message received. It may be anything but the value has to be present in JSON.

Hi @rshubham Thanks for the feedback, we will investigate this further and let you know about the findings soon

[Ved2806]

Hi @rshubham Please try using following JSON.
{ "name" : "request", "queueName" : "my-queue", "connection" : "storage-conn-string" } Please let us know if it helps. Thanks.
