I have the SendBird Chat installed and working with my ReactNative app for months now. I am attempting to install and use SendBird Calls. Even though SB Chat supports authentication with only a user id (via
connect method), apparently the SB Calls requires an access token. At this point I already have several users of my app, thus several users with SB accounts. None of those users have ever been issued an SB access token because up until this point I didn’t need to issue one. When I attempt to issue an access token for an existing user, via instructions found here, I am always getting a 400 server error, particularly a 400401 INVALID_API_TOKEN error. How can I issue a token for an existing user that never had a token issued if I am required to pass a token to issue a token? What am I missing here?
