Theme plugin not working after update to 2.2.4

Hi, when I updated Indico to version 2.2.4 the plugin for customization themes for events and conference stopped working.
This plugin is based on plugin developed at CERN (https://github.com/indico/indico-plugins-cern/tree/master/themes_cern).
I get next error - “OSError: [Errno 2] No such file or directory: ‘/opt/indico/.venv/local/lib/python2.7/site-packages/indico_themes_jinr/static/dist/manifest.json’”
The error occurs again after rebuilding the plugin with build-wheel.py.
Can Your help me?

On which branch is your indico clone from which you use build-wheel.py? It should be 2.2-maintenance, since the build process changed in 2.2. master would work as well (in theory) but since that’s 2.3 development there are absolutely no guarantees that it does work when building something for 2.2.
