Azure Function Service Bus Queue Trigger - "A host error has occurred. System.Private.Uri: Value cannot be null. Parameter name: uriString."

Question

I have created an Azure Function (V2, .NETCore) for Service Bus Queue Trigger. But I am getting below error while running the project.Please find below the screenshots.

local.settings.json

Error-1

Error-2

My Function Code is given below.

using System;
using Microsoft.Azure.WebJobs;
using Microsoft.Azure.WebJobs.Host;
using Microsoft.Extensions.Logging;

namespace FunctionTriggers
{
    public static class Function1
    {
        [FunctionName("Function1")]
        public static void Run([ServiceBusTrigger("myqueue", Connection = "ServiceBusConnString")]string myQueueItem, ILogger log)
        {
            log.LogInformation($"C# ServiceBus queue trigger function processed message: {myQueueItem}");
        }
    }
}

Could you please check if you have provided the right service bus connecting string? Regarding how to get it, please refer to docs.microsoft.com/en-us/azure/service-bus-messaging/… — Jim Xu
@JimXu : I have added the correct connection string in local.settings.json — user12462814
@JimXu: I have updated question with screenshots of local.settings.json and one more error for reference. — user12462814
According to the picture you provide, the value of ServiceBusConnString is also the storage account connection string. Please use service bus connection string. It should be like Endpoint=sb://<your service bus name>.servicebus.windows.net/;SharedAccessKeyName=RootManageSharedAccessKey;SharedAccessKey=<your share key>. Regarding how to get it, please refer to docs.microsoft.com/en-us/azure/service-bus-messaging/… — Jim Xu

If you want to use the Azure function service bus trigger, we must provide the Service Bus ConnString. The connection string should be like Endpoint=sb://<your service bus name>.servicebus.windows.net/;SharedAccessKeyName=RootManageSharedAccessKey;SharedAccessKey=<your share key>. Regarding how to get it, please refer to https://docs.microsoft.com/en-us/azure/service-bus-messaging/service-bus-quickstart-portal#get-the-connection-string.
