There is a fundamental difference between Jira Server/Data Center and Jira Cloud: In Jira Cloud post functions of apps are executed asynchronousasynchronously as a 'background job'. This means a post function will be executed after the transition has been completed on Jira Cloud.
...
Note the following behaviors of the asynchronous execution:
- If you are using multiple post functions, there is no guaranteed order in which several post functions they are performed. They might be executed in a different order from the one you had set them up in Jira's workflow configuration. So Therefore, you cannot rely on any result of a 'previous' post function. The Also, the order by in which the post functions are executed might be different every time the transition is performed.
- When If a post function has encounters a problem (due to misconfiguration or the current data of a Jira issue), the transition (and all other post functions) will be performed neverthelessregardless of the problem.
- The result of a post function might not be visible immediately in the browser.
- There are no error messages displayed to the user.
