[outreachy][cinder] Unable to generate api-ref samples for snapshot transfer

Hi, I am trying to generate api-ref doc from template by running "tox -e snaphot_transfer" but I keep getting the same error pasted in the link https://paste.openstack.org/show/bFPbWKQAKRbIds4R0wWn and I have installed the missing dependency as shown below, anyone have an Idea what the issue could have been? Thanks for your time. [image: image.png]
