The specified container does not exist (Azure)

Code below works. But when i'm trying to delete blob from container i`m getting exception "The specified container does not exist":

public static async Task Run([BlobTrigger("files-for-uploading/{name}", Connection = "AzureWebJobsStorage")]
        Stream myBlob, string name, ILogger log)
{
    try
    {
        var config = new ConfigurationBuilder()
            .AddJsonFile("local.settings.json", optional: true, reloadOnChange: true)
            .AddEnvironmentVariables()
            .Build();

        if (CloudStorageAccount.TryParse(config["AzureWebJobsStorage"],
            out CloudStorageAccount storageAccount))
        {
            ClientHandler clientHandler = new ClientHandler(HttpClientFactory.Create());
            CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient();
            CloudBlobContainer container = 
            blobClient.GetContainerReference(config["ContainerForFileUploading"]);
            DeleteFilesFromBlob(container, name, log);
        }
    }
    catch (Exception e)
    {
        throw;
    }
}

Delete function:

private static void DeleteFilesFromBlob(CloudBlobContainer container, string blobName, ILogger log)
{
    CloudBlob file = container.GetBlobReference(blobName);
    file.DeleteIfExists();
}

And it delete works when i'm running it in Visual Studio, but does not work in azure. Very strange.

The parameter to GetBlobReference should be the name of the blob and not the fileUrl.

The following code Im using myself and it works.

    public async Task<IActionResult> delete(string blobName)
    {
        string blobstorageconnection = _configuration.GetValue<string>("blobstorage");
        string blobContainer = _configuration.GetValue<string>("blobcontainer");

        CloudStorageAccount cloudStorageAccount = CloudStorageAccount.Parse(blobstorageconnection);
        CloudBlobClient cloudBlobClient = cloudStorageAccount.CreateCloudBlobClient();

        CloudBlobContainer cloudBlobContainer = cloudBlobClient.GetContainerReference(blobContainer);
        var blob = cloudBlobContainer.GetBlobReference(blobName);
        await blob.DeleteIfExistsAsync();



        return View();
    }
