So you open the game, go into friend requests to accept a friend request as usual, the accept friend request button does nothing this time around. You go onto the [url=https://www.bungie.net/7//User/Account/BungieFriends]website[/url], in an attempt to accept it there, and guess what, there's also no error handling. A vague, [i]Friend request failed[/i], response's given in the frontend. If you check the post request sent, there's a friendly human-readable error sent within the [i]message[/i] property of the API's response, telling you, [i]The request has failed; Your friend list is full.[/i] This needs to be relayed, both in the frontend, and within the game.
