What problem was encountered?

I am not able to retrieve blobs because an exception is being thrown by the library: DeserializationError: Unable to deserialize to object: type, KeyError: 'name'

How can we reproduce the problem in the simplest way?

Take a container with some files in it, then with ipython do:

In [1]: from azure.storage.blob import BlobServiceClient, BlobClient                                                                                       

In [2]: ASA_CONNECTION_STRING = "DefaultEndpointsProtocol=https;BlobEndpoint=https://<<SOMETHING>>.blob.core.windows.net/;AccountName=<<SOMETHING>>;AccountKey=<<SOMETHING_ELSE>>"                                              

In [3]: ASA_CONTAINER_NAME = "<<SOME_NAME>>"                                                                                            

In [4]: blob = BlobServiceClient.from_connection_string(ASA_CONNECTION_STRING)                                                                             

In [5]: container = blob.get_container_client(ASA_CONTAINER_NAME)                                                                                          

In [6]: stuff = container.list_blobs()

In [7]: thing = stuff.next()

Then you'll see: DeserializationError: Unable to deserialize to object: type, KeyError: 'name'.
It seems to be coming from the package msrest which I am assuming is a dependency for this package.

Have you found a mitigation/solution?

No - I am trying to find alternatives to filter blobs from a blob storage or containers, but so far no luck.

For some reason if I uninstall all the pip packages containing the string "azure" with this:

for i in `pip list | awk '/azure/ {print $1}'`; do pip uninstall -y $i ; done

Then I remove this msrest package (version msrest-0.6.10) with:

pip uninstall msrest

Then I install again this package azure-storage-blob:

pip install azure-storage-blob --upgrade

Then the code snippet above to retrieve a blob works.

The interesting fact is that this msrest is re-installed with the version msrest-0.6.19.
There must be something wrong with msrest-0.6.10 that is not captured by the requirements for azure-storage-blob.

Apologies for mixing Go with Python. I am closing this issue, but opened it in the relevant Python repository for the SDK: Azure/azure-sdk-for-python#16250
