Azure-sdk-for-net: [BUG] Storage container CreateIfNotExistsAsync -> null exception in Azure.Core if container already exists

Created on 31 Jan 2020 · 14Comments · Source: Azure/azure-sdk-for-net

Describe the bug
Getting null exception from Azure.Core if trying to create a blob container that already exists, but I am using CreateIfNotExistsAsync.

Expected behavior
CreateIfNotExistsAsync succeeds

Actual behavior (include Exception or Stack Trace)
CreateIfNotExistsAsync succeeds if container does NOT already exist, but throws null exception if container DOES already exist.

To Reproduce
Steps to reproduce the behavior (include a code snippet, screenshot, or any additional information that might help us reproduce the issue)

Create BlobServiceClient instance
Create containerClient by calling client.GetBlobContainerClient, with a container name
await containerClient.CreateIfNotExistsAsync(cancellationToken: cancellationToken);

If the container ALREADY EXISTS, it results in this Exception:

System.NullReferenceException
HResult=0x80004003
Message=Object reference not set to an instance of an object.

issue #109 has existed for 8 years (!) and seems to be the exact same thing.

As mentioned by @hallgeirl all sorts of methods that should not throw are throwing exceptions.

After looking a the stack a little bit seems that the exception is happening in the application code. Can you provide a snippet of code that calls the container client?

pakrym on 1 Feb 2020

Nothing special:

var containerClient = this.Client.GetBlobContainerClient(
    blobContainerName: containerName);

return await containerClient.CreateIfNotExistsAsync(
    publicAccessType: PublicAccessType.Blob,
    cancellationToken: cancellationToken);

zmarty on 7 Feb 2020

I think one scenario where this occurs is:

Manually delete a container that has multiple files in it.
Run code that tries to recreate it with CreateIfNotExistsAsync
Exception is caused by the fact that Azure infrastructure has not in fact finished to delete it

Can you try to repro this and make it handle this better or throw a more reasonable Exception?

Thanks!

I have the same issue - but we've not deleted anything. We're trying to use CreateIfNotExists() on a container that has existed for years. Exists() also crashes with a NullReferenceException.

Here's our code:

            var c = new BlobContainerClient(_connectionString, container);

            if (!await c.ExistsAsync())
                await c.CreateAsync();

We've tried with both c.CreateIfNotExists, and the below approach - same result. "container" is the name of our container, which exists, and _connectionString is a correct and valid connection string for the storage account.

Edit: Seems like Exists() works - could it be the async API that is broken?

issue #109 has existed for 8 years (!) and seems to be the exact same thing.

As mentioned by @hallgeirl all sorts of methods that should not throw are throwing exceptions.

Agreed. Our Azure logs have 3,000 + entires of 409's because of this.

Same, thousands of errors, sure the Azure team should want to fix this? Looks like it needs to use the List Containers first to check if it exists:

Hi,

For @zmarty 's scenario where you create a container with blobs, delete them and then call CreateIfNotExists afterwards. I was able to reproduce the scenario you are describing where you get a "ContainerBeingDeleted" Error. There's not much we can do when the storage service is still in the process of deleting the container. If we catch that exception too it would be a misleading exception to catch and hide from the user because the user should be aware of the exception that the service needs to time to delete the container. What's a more reasonable exception aside from "ContainerBeingDeleted"?

Also I'm still trying to recreate your original scenario but I'm unable to recreate it. Could you enable logging and maybe we can see what the request is returning and maybe we can get to the bottom on why Azure.Core is returning the exception it is returning.

https://docs.microsoft.com/en-us/dotnet/azure/sdk/logging

For @hallgeirl scenario, could you also enable logging as well and maybe we can see the requests as well? Also a stack trace would be helpful as well.
For @daviesro and @matt40k Could you get the error code message that appears with the 409? How CreateIfNotExists functions is that it is a convenience method that attempts to Create the container, and if the container exists, it will throw a 409 and the client storage SDK will catch the exception for you. Unfortunately there's no REST API call that just calls to check the existence.

https://docs.microsoft.com/en-us/rest/api/storageservices/operations-on-containers

It is as intended and expected that a 409 will be thrown and be in your logs, if you call this method and the Container does not exist. Even if an Exists REST API does exist, it would be not ideal for there to be a call to check existence and then a call to create the container. It would require two calls to storage instead of one call.

Thanks Amanda. It's possible that we are getting ContainerBeingDeleted in the specific case where we are trying to delete something that is being deleted. My recollection is however that we were getting a non specific Exception. But maybe that applies only to other instances where we still see this error outside of this very narrow case. We still experience this problem when we are NOT deleting anything.

We do use logging in Azure Functions through Application Insights. Is that enough to capture everything you need?

zmarty on 15 May 2020

Hi @zmarty ,

What I'm looking for in the logs is the request that the SDK is sending (when calling CreateIfNotExists on a container) and the response it is getting back by sending this request. You can also include the log for the scenario ContainerBeingDeleted, if you see an error aside from that one. I want to investigate the response we are getting back to cause an exception like this (or request we are sending).

Something like this:

If the logs from Azure Functions show this, that would be helpful, that would suffice.

amnguye on 15 May 2020

We are also still getting this periodically in the logs.

@amnguye I looked in our logs when this happens and I see that we call CreateIfNotExistsAsync, which results in the null exception.

Internally what happens is that there is an HTTP PUT request to https://SOMETHING.blob.core.windows.net/some-name-2020-05-22?restype=container and the storage API returns HTTP 409 Conflict Hopefully that gives you a clue as to what is going on. I will also send you an internal e-mail with more screenshots.

Hi @pakrym @tg-msft ,

Could you help me out with this? Some customers are seeing an NullReferenceException being thrown in Azure.Core. This happens more frequently for the customers. I am not able to reproduce it even with multiple retries to see if it happens intermittently.

I confirmed with the customer was able to confirm that the service gives them a 409 - ContainerAlreadyExists response. However the NullReferenceException happens before the CreateIfNotExists is able get the ErrorCode. It might be happening when it's attempting to create the response.

amnguye on 28 May 2020

A quick skim here makes me think it's happening because CreateIfNotExists returns null for ContainerAlreadyExists and then Response<T>'s implicit cast to T fails to unwrap a null response. If that's the case, then

```C#
await container.CreateIfNotExistsAsync(...); // Make sure it already exists
BlobContainerInfo containerInfo = await container.CreateIfNotExistsAsync(...);

should fail here with a nullref when the `Response<BlobContainerInfo>` is implicitly unwrapped.  A workaround would be replacing it with 

```C#
await container.CreateIfNotExistsAsync(...); // Make sure it already exists
Response<BlobContainerInfo> response = await container.CreateIfNotExistsAsync(...);
if (response != null)
{
    BlobContainerInfo containerInfo = response.Value;
    // ...
}

@amnguye - Can you try that out? If that's what's wrong, we can brainstorm whether there's something better to return here.

tg-msft on 28 May 2020

👍1

@tg-msft Just tried that out, yeah I was able to get the NullReferenceException, I'm not sure what would we would replace default with though. I'm open to suggestions.

catch (RequestFailedException storageRequestFailedException)
when (storageRequestFailedException.ErrorCode == BlobErrorCode.ContainerAlreadyExists)
{
     response = default;
}

I might have to make the fix to all the CreateIfNotExists/DeleteIfExists/Exists methods too.
