I believe the error may have been caused by something else in your code. As for the API, everything seams to be functioning properly on my end. If you would like some help debugging your code you can message me (click on my name, then message.) or link me to your GitHub. I’d be happy to help.
by the way… are you authenticated as se7ensinslivestream, because if the channel broadcaster is not a partnered channel and they have your account set as Editor, you wont be able to make changes to the channel status/game/ect.
