Config value 'plugins': Plugin 'i18n' option 'languages': Expected a list of items, but a <class 'dict'> was given.

Two months ago, I successfully deployed a webpage on GitHub Pages using this plugin. Today, when I modified the webpage, Action reported an error. My webpage can be deployed and browsed locally, but it cannot be deployed to GitHub Pages.
