Why do I get an NLChannelGatewayErrorDomain error when I try to use LINE Login in my application?

NLChannelGatewayErrorDomain errors (for example, NLChannelGatewayErrorDomain Error 102) can occur if there are incorrect or missing settings in the LINE Developers Console.

If your iOS application is getting this error, confirm the following items:

The iOS bundle ID is registered on the LINE Login tab of your channel settings on the LINE Developers Console
The iOS universal link is registered on the LINE Login tab of your channel settings on the LINE Developers Console
The LINE account that you are using to log in with is registered in the Roles section of the LINE Developers Console
