@Bha2912 Please fix localization - see https://devdocs.jabref.org/code-howtos/localization.html for help

  PASTE THESE INTO THE ENGLISH LANGUAGE FILE "JabRef_en.properties".
  Search for a proper place; typically related keys are grouped together.
  If a similar key is already present, please adapt your language instead of adding load to translators by adding a new key.

Using exceptions for control flow is not recommended. Instead, handle the absence of a database more gracefully without throwing a NullPointerException.

Jsut use get() or - even better: stateManager.getActiveDatabase().ifpresent( ...)

@trag-bot didn't find any issues in the code! ✅✨

You committed your code on the main brach of your fork. This is a bad practice. The right way is to branch out from main, work on your patch/feature in that new branch, and then get that branch merged via the pull request (see GitHub flow).

For this pull request, this is OK. For subsequent pull requests, please start with a different branch with a proper branch name. See CONTRIBUTING.md for more details.

Please re-read the issue description again

You should try to make use of org.jabref.logic.util.BackgroundTask#updateProgress(double, double)

See other code how this is done...

I think, the best example is org.jabref.gui.citationkeypattern.GenerateCitationKeyAction#generateKeysInBackground
