It means there was an error during a database operation (between bonita & your postgres database). Basically it says a transaction has been rolled back.
As to "why?", "what transaction?" and "is it something to worry about?", we will need the rest of the stacktrace.
Yes you are right the prob;lem is with the database which i added in postgres, when I delete the data it's wowrking fine
I think the problem is with persistenceId, because whatever persistenceId which I am adding from backend is already present in my data and due that it's throwing the error.
So what's the solution for that to create a persistenceId , max+1 in backend?
The persistenceId is generated automatically by bonita.
Inserting data manually in the database is not supported. If you want to populate your database, you need to do it through the API/bonita portal.
