In the fresh server I saw that frappe version and erpnext version aren’t the same.

then I run
sudo bench switch-to-branch version-12 --upgrade
and got both in version-12
I run this
bench reload-doc Core Doctype milestone_tracker
but I got this message
/apps/frappe/frappe/core/doctype/milestone_tracker/milestone_tracker.json missing
I dunno what else to do.
Any one with a suggestion?
