During a Jira migration to a new Jira Data Center instance where issue keys remain the same as in the previous instance”I am attempting to associate preconditions, test sets, and test plans to a test case using the JIRA APIs, following the official documentation precisely. However, when I use, for example, PUT server/rest/api/2/issue/testkey to associate customfield_id preconditions, test set, test plan and sending a correct json I encounter a null pointer exception stating: a cannot invoke java.lang.Integer.intValue because parameter 2 is null, and the API call returns a 400 error code along with the corresponding log trace. java.lang.NullPointerException: Cannot invoke \"java.lang.Integer.intValue()\" because parameters 2 is null"],"errors":{}}
I have verified that all the custom fields are present on the screens, performed both background and full re-indexing, and even implemented retry mechanisms, but nothing has worked. Interestingly, when I manually open the ticket in the Jira browser and then rerun my script without modifying the code, the request succeeds for that ticket (returning a 204 no content status code).
Since I have approximately 4600 test issues, manually opening each one is not possible
Could you please help identify the cause of this issue and suggest a possible resolution?
