What problem was encountered?

I am getting an error when trying to read a blob from bytes, it doesn't throw any exception though and it doesn't even say which file causes the problem. The error is:

Client-Request-ID=ab8ef66e-6bdc-11e9-9e3e-14109fe2857d Retry policy did not allow for a retry: Server-Timestamp=Wed, 01 May 2019 06:45:12 GMT, Server-Request-ID=48639d1f-e01e-0017-18e9-ff2e34000000, HTTP status code=416, Exception=The range specified is invalid for the current size of the resource.

So in this code, I am listing all the blobs, and then downloading them to the folder. The problem happens in the loop, at the third loop or so I get that error.

Hi @akshaybabloo

Hopefully you've found a workaround for this problem. Would you like to use debug mode and locate where the error exactly happens. Here is how I test and it's working for me.

    self._create_block_blob()
    self._create_block_blob()
    blob_list = self.bs.list_blobs(self.container_name)

    #Assert
    for blob in blob_list:
        self.assertTrue(blob.properties.server_encrypted)

I believe this error is shown when you try to download a zero-length blob. You can get around it by checking the blob properties prior to trying the download, or alternatively just let it happen - the file is downloaded as it should be anyway.

@lyceus ya you are right. Should have checked it. Thank you.
