Azure Function: Blob identifiers must be in the format 'container/blob'

Question

I have created an Azure Function using the BlobTriggerCSharp example and configured the storage account and path:

I double checkt that there is a mbrtest container within the configured storage account:

I didn't changed anything else. Here is the run.csx:

public static void Run(Stream myBlob, string name, TraceWriter log)
{
    log.Info($"C# Blob trigger function Processed blob
 Name:{name} 
 Size: {myBlob.Length} Bytes");
}

When I press the run button, I get the following error:

2017-05-12T13:47:35.567 Exception while executing function: Functions.BlobTriggerCSharp1. Microsoft.Azure.WebJobs.Host: One or more errors occurred. Exception binding parameter 'myBlob'. Microsoft.Azure.WebJobs.Host: Blob identifiers must be in the format 'container/blob'.

Any hints?

I followed the solution of Mikhail with the three steps plus the configuration of the Function App.

You have to go to the Settings pannel in the left grid and click over "Configuration". Then I had a variable called AzureWebJobsStorage which was incorrect, so edit it and fill it with the parameters of the storage account. You can find them on the storage account in the Access Keys option.

The value that you need to add is something like this: (note that it is an example not a valid key) DefaultEndpointsProtocol=https;AccountName=YourAccountNameHere;AccountKey=RandomVerylong......stringVwithuninteligiblevalues)!%;EndpointSuffix=core.windows.net

This value shoulde go in the value of this setting variable
