JIRA throwing "Internal Server Error" after editing an Issue

[Maximlian Thorand]

Hello there,

i'm trying to edit two customfields via REST API in JIRA. I did not have any problems until i got this Internal Server Error Message.

Here's what i'm sending via "PUT" request (just for one customfield)

foreach (var s in beobachterInKopie)
            {
                objJira.JiraJson = "{                                                                         " +
                                        "\"update\": {                                                        " +
                                            "\"customfield_13156\": [{                                        " +
                                                            "\"add\": {\"key\": \"" + s + "\"}                           " +
                                                         "}]                                                  " +
                                                    "}                                                        " +
                               "}";
                response = objJira.manipulateIssue();
            }

I'm not facing any problems with the code, just can not handle that Error message somehow? What am i doing wrong here? Or does the admin of the project (JIRA) need to unlock something? Can not find anything online concerning this problem either...

Hi Maximlian,

Please check logs to find out the actual problem. There may be a problem in your put method at the backend.
