Fatal Exception: java.lang.RuntimeException: Unable to start activity ComponentInfo{/com.linecorp.linesdk.openchat.ui.CreateOpenChatActivity}: java.lang.IllegalArgumentException: channel id is empty

Start by reproducing the launch failure in com.linecorp.linesdk.openchat.ui.CreateOpenChatActivity and trace how the channel ID reaches that activity. Confirm why the reported non-empty ID becomes empty; done means the activity launches without this IllegalArgumentException for the reported case.
