Troubleshooting

This document covers the errors that may occur when implementing or calling the Kakao Talk Social APIs and their solutions. If you cannot find the error you encounter, see Response code.

Common

If the number of friends passed in response is less than the number of selected friends

The total count of friends a user selected (selectedTotalCount) on the multi-picker may differ from the number of friends passed in the response (SelectedUser).

• Example case: a user A selects the user's friend B on the Friend picker. → Before the request to retrieve friends on the Friend picker is completed, B unlinks from the app. → A selects [Ok] on the Friend picker to request the friend data.
• Result: B who selected on the Friend picker is counted as selectedTotalCount but not included in the response to the request of the friend information.
• For this case, you must notify users that the retrieved friend data is less than the number of friends they selected, considering users' better experience.
