What problem was encountered?

I have the following file structure in my blob container:

• my-test-directory/
• • file1.jpg
• • file2.jpg
• • nested/
• • • file1.jpg
• another-directory/
• • file1.jpg

When I run container_client.list_blobs(name_starts_with='my-test-directory/') I somewhat expect the following blob to be listed:

• my-test-directory/file1.jpg
• my-test-directory/file2.jpg
• my-test-directory/nested/file1.jpg

However, what I am getting is the following:

• my-test-directory
• my-test-directory/file1.jpg
• my-test-directory/file2.jpg
• my-test-directory/nested
• my-test-directory/nested/file1.jpg

As you can see, the directories are included in the blob listing as well, as if they are blobs.

How would one exclude directories from the listing, so only paths to actual blobs are returned?
