Plugin featuredviews not working

[joelriverac]

I have installed the featuredviews plugin in ckan 2.9 (latest version), package installation in Ubuntu Server LTS 20.04 (local server), but it does not work, let me explain

I install plugin

git clone https://github.com/cbgaindia/ckanext-d3view.git
git checkout dev
python setup.py develop

It installs without problems, two buttons are shown when viewing the dataset, but when pressing them, nothing happens, nor is the dataset displayed on the main screen.

My plugins in ckan.ini are the following

ckan.plugins = stats text_view image_view recline_view datastore xloader viewhelpers featuredviews pages recline_grid_view recline_graph_view recline_map_view webpage_view datastore_refresh pdf_view visualize

ckan.views.default_views = image_view text_view recline_view mimetypes xloader recline_grid_view recline_graph_view recline_map_view webpage_view pdf_view

I see no error, I update the database with the command
ckan -c /etc/ckan/default/ckan.ini featured initdb

The warning that the featured views table already exists, I understand that it is because I already executed the database update command before

Am I doing something wrong? or is it a plugin problem?
