I always got “null” error message when publish an app. While there is no exception.
The backend log:
Hi,
any log? Could you add exported app too?
Regards
Martin
Look in the catalina.out log inside of tomcat.

I did not find any error message in the attached log.
Thanks for all reply, due to my new account was under audit, I just posted the log. Please help to check.
Like Martin explained, there is no error in that log.
Did you check if there’s an error in the Publish app call (see network traffic in your browser)?
Best regards,
Tijs
Dear,
There is no error, while return null message. The log says Transaction marked as rollback without more detail.
Due to this problem, I have downgrade to 6.1.2 and everything works well.
Hmm, downgrading to an older version is obviously not nice 
Is there any way you can share the app so we can have a look why it fails on 6.2.0?
I guess it is the defect fixed by https://github.com/flowable/flowable-engine/commit/138d391d0dc173e295dd16118d7a4ef07f213137
This defect makes it impossible to publish an app without any case definitions (e.g. just a process definition) in 6.2.0.
Hi,
The 6.2.0 download in Github and on the website contains the fix. It’s based on this branch:
We’ll do a 6.2.1 release also containing this fix shortly, hopefully next week.
Best regards,
Tijs
Thanks, then I will upgrade to this version to check.
If the 6.2.0 download already includes the fix and johnny2002 did not build from source than the problem johnny2002 encountered can’t be the one I mentioned above. Sorry!
