Cannot proceed with update: You have local changes in app “erpnext” that are not committed.
Here are your choices:
Merge the erpnext app manually with “git pull” / “git pull --rebase” and fix conflicts.
Temporarily remove your changes with “git stash” or discard them completely
with “bench update --reset” or for individual repositries “git reset --hard”
If your changes are helpful for others, send in a pull request via GitHub and
wait for them to be merged in the core.
