JSONObject["time_entry"] not found when using TimeEntryManager.createTimeEntry

[seeker1977]

Hi, my program works usually OK when i use my own API key or some of my colleages. But when I use my boss api key, I get this error when trying to use createTimeEntry:
com.taskadapter.redmineapi.RedmineFormatException: org.json.JSONException: JSONObject["time_entry"] not found.
at com.taskadapter.redmineapi.internal.Transport.parseResponse(Transport.java:612)
at com.taskadapter.redmineapi.internal.Transport.addObject(Transport.java:231)
at com.taskadapter.redmineapi.TimeEntryManager.createTimeEntry(TimeEntryManager.java:74)

Does anyone know why is this happening and how to fix it? It looks like a user config related issue, but I don't know how to solve it...
