GRAV - SitemapEntry not found


I don’t know if that’s related to new GRAV updates, but since some weeks ago, sitemap plugin show me an error when i try to acces /sitemap page from my testing evironement.

Class ‘Grav\Plugin\Sitemap\SitemapEntry’ not found

From my workflow, i’m using local, testing, preview then live server.

From local all good, then i push changes to GIT system and deploy to testing ( server ) mode.

I’m asking, is it composer version ( error ), plugin sitemap ( error ), files sent to git are not fully updated.

Please to advice me.
