If you click the "Details" button, you should see a copy of the actual error. If you can share this, it will help us solve the problem.
In most cases, the error will be because of different versions of the same .jar file in the userlib. This usually occurs when modules are upgraded or new modules are added. To check for this, look in your application's userlib folder, and look for any .jar files with the same name but with different version numbers at the end of their filename. If you see any duplicates, delete the ones with the lowest version number.
Good luck!
Hi Sai,
This usually happens if your local setup is out of sync. A few quick things to try:
Do a Clean Deployment Directory in Studio Pro and re-run.
Make sure you’re using the right JDK version (Mendix 9/10 needs AdoptOpenJDK 11 or 17 depending on your app).
Check if there are any duplicate or missing JARs in userlib.
If teammates recently changed Java actions, pull the latest code and update.
Worst case, try a fresh clone of the repo.
If you can share the exact error message . it’ll be easier to point to the exact issue.

This looks like the Community Commons module in your application is missing some .jar files. To fix this, I would reinstall the Community Commons module from the Marketplace. This should bring in the required .jar files to your userlib / vendorlib.
I hope this helps.
