Azure-functions-host: The binding type(s) 'queueTrigger' are not registered.

[danielzoeller]

When I run my very basic C# function locally, it will not work with queueTrigger input bindings. It will compile but it will not run. I get the error:

Function1: The binding type(s) 'queueTrigger' are not registered. Please ensure the type is correct and the binding extension is installed.

This wasn't a problem for me several weeks ago before I upgraded to the latest version of everything. And I definitely DO have the Microsoft.Azure.WebJobs.Extensions.Storage nuget package installed.

What I'm running:
Azure Functions Core Tools 2.3.199
Function Runtime Version: 2.0.12246.0
Functions SDK 1.0.24
netcoreapp2.2
VS2017

I have two functions defined. The one set up with QueueTrigger input will not work. My second function which uses a TimerTrigger works fine.

using System;
using Microsoft.Azure.WebJobs;
using Microsoft.Azure.WebJobs.Host;
using Microsoft.Extensions.Logging;
using Microsoft.WindowsAzure.Storage.Table;

namespace FunctionAppTest
{
    public static class Function1
    {
        [FunctionName("Function1")]
        public static void Run([QueueTrigger("myqueue-items", Connection = "defaultConnection")]string myQueueItem, ILogger log)
        {
            log.LogInformation($"C# Queue trigger function processed: {myQueueItem}");
        }

        [FunctionName("FunctionTimer")]
        public static void Run2([TimerTrigger("0 * * * * *")] TimerInfo timer, ILogger log)
        {
            log.LogInformation($"C# Queue trigger function processed: {timer}");
        }
    }
}

Console window gives me this output:

Here is what my solution looks like:

What I've tried:
I've tried changing frameworks to .net core 2.1 and 2.0, even .net standard 2.0.
I've tried rolling back to previous nuget versions of the various packages (3.0.1 and 3.0.0 of storage extensions, 1.0.23 of functions sdk, 9.3.1 of azure storage).
I've tried manually starting my function using the functions host (func.exe).

FWIW, I get the same error if I try to use Cosmos DB input bindings.

This is obviously not a production app but my real app is having the same issue when I run it locally and I do need it working in production very soon. Any help would be GREATLY appreciated!

Thanks,
Dan

[alexhitchins]

I too am having exactly this issue. Did you manage to get it to work in the end or are you still looking for assistance?

If anyone can provide any input I'd be extremely grateful.

[danielzoeller]

No, I never figured it out. I narrowed it down to a nuget problem (I think) but I ended up having to basically wipe my machine and reinstall everything (vs2017, .net core, etc). It was as if my development machine had become very confused on where to look for nuget packages.

[Aditi-Kradle]

I am also getting
Exception thrown: 'System.Threading.Tasks.TaskCanceledException' in System.Private.CoreLib.dll
IScriptJobHost
IOptions`1

in DEBUG window when I run my azure functions locally, but that does not stop my function from running. It works perfectly but I am not sure how that error is coming, there is surely something wrong but it does not give any exception, it just logs in the DEBUG output window vs 2017

I am also encountering this issue. V1 functions are fine, it's V2 causing an issue. HttpTrigger binding is fine, QueueTrigger binding gives the dreaded "The binding type(s) 'queueTrigger' are not registered. Please ensure the type is correct and the binding extension is installed." I have the Microsoft.Azure.WebJobs.Extensions.Storage NuGet package installed as well.

[davidkassa]

@Furynation same for me and it's driving me nuts! One thing I'm finding strange that I'm digging into is my Azure Functions Core Tools say they're version 2.4.379 (hash: ab2c4db3b43f9662b82494800dd770698788bf2d) but it appears the latest is 2.4.317. Not sure if it's related but what I'm digging into now.

[davidkassa]

This is (mostly) working for me. https://github.com/Azure/Azure-Functions/issues/928#issuecomment-466093874

[dhensby]

Have you installed the extensions (https://docs.microsoft.com/en-us/azure/azure-functions/functions-run-local#register-extensions)?

func extensions install

[amieres]

What worked for me was creating a file called extensions.json like this:

{
  "extensions":[
    { "name": "AzureStorage", "typeName":"Microsoft.Azure.WebJobs.Extensions.Storage.AzureStorageWebJobsStartup, Microsoft.Azure.WebJobs.Extensions.Storage, Version=3.0.5.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"}
  ]
}

and placing it in the bin folder with the .dlls

[RobinTTY]

I had the same problem in a project I'm working on and was able to narrow down the cause of this.
In my case a custom nuget.config file was causing the problem, which looks like this (actual package sources removed):

<?xml version="1.0" encoding="utf-8"?>
  <configuration>
    <config>
      <add key="globalPackagesFolder" value=".\packages" />
    </config>

    <packageSources>
        <clear />
        <add key="someLocalTfsServer" />
        <add key="anotherLocalTfsServer" />
        <add key="nuget.org" value="https://api.nuget.org/v3/index.json" protocolVersion="3" />
    </packageSources>

    <disabledpackagesources>
        ...
    </disabledpackagesources>

</configuration>

The specific line which is causing the problem is:

<add key="globalPackagesFolder" value=".\packages" />

When removing the line defining the global package folder my problem was gone, I was able to reproduce this every time I added the line back. I'm not sure what is causing this behaviour since the required package (in my case microsoft.azure.webjobs.extensions.storage) exists in the global packages folder.

The output also contains an interesting FileNotFoundException (excerpt):

IEnumerable`1
ScriptHost
ScriptHost
Exception thrown: 'System.IO.FileNotFoundException' in System.Private.CoreLib.dll
'func.exe' (CoreCLR: clrhost): Loaded …
….
….
IScriptJobHost

So it seems like it might not find the required package when the package folder is higher up (or just not at the default location) in the project hierarchy. This exception does not occur when I use the nuget.config without the globalPackageFolder definition.

[JustinGrote]

In my case it looks like the format and storage of extension bundles changed between versions. I just went into my AppData\Local\Temp\Functions folder and renamed the existing extension bundles to disabled, and it redownloaded them and then worked fine.

Probably a breaking change that didn't get detected in QA.

[ArpitLabs]

I had the same error "The binding type(s) 'queueTrigger' are not registered. Please ensure the type is correct and the binding extension is installed." with output log

Exception thrown: 'System.IO.FileNotFoundException' in System.Private.CoreLib.dll
'func.exe' (CoreCLR: clrhost): Loaded …

Not exactly sure what was wrong but I updated all nuget packages for which an updated version was available and it worked.

[PetrPospisil]

Try to erase your C:\users[user]\AppData\Local\Temp\Functions as it is the place where the VS2017 stores binding bundles. It solved my issue.

[pragnagopa]

Closing this issue as the details here mix of using bundles and not using bundles. Please open separate issue.
@ArpitLabs - please open separate issue with repro details including if you are using extension bundles or not.
