Error updating database. Cause: org.postgresql.util.PSQLException: ERROR: update or delete on table "act_ru_execution" violates foreign key constraint when using parallel and sub process flow

Hello, I have a problem when using parallel and sub process flow on camunda pipleline, so there is an edge case on production environment (can’t reproduce it on local environment) when camunda engine want’s to delete the executions it still referenced from table act_ru_execution, can anyone please help me with this, thanks :pray:

Below is my bpmn tree diagram

Can you take a look at the Style Guide? It’ll help you understand how to format code correctly and also help you create questions that are easy to understand and also easier to answer :slight_smile:

oo yeah sure, thanks :pray:

Can you also upload you model?
And give more details about what you Camunda setup is?

Sorry for late response, I found out the issue is happen because I’m using the subprocess and terminate end event on it, so when the subprocess is done the camunda engine will try to delete the subprocess act_ru_execution row, but it still referenced to the main process because it’s not done yet.

anyway my camunda setup is using springboot applications, thanks for your response @Niall :pray:
