**Brief description** When sending a PubSub Broadcast, if the topic/target is s…omething besides "broadcast" or "global" (for example, "whisper-opaque_user_id"), the broadcast is not received by simulated user views in the Developer Rig. **How to reproduce** Frontend code to listen for broadcasts: ``` twitch.onAuthorized(function (auth) { twitch.listen('whisper-' + auth.userId, function (targ, cType, message) { twitch.rig.log(message); // this is never hit }); }); ``` Backend code to send a PubSub broadcast (C#): ``` public async Task SendPubSubWhisper(string channelId, IEnumerable<string> userIds, string message) { using var request = new HttpRequestMessage(HttpMethod.Post, $"https://api.twitch.tv/extensions/message/{channelId}"); request.Headers.Add("Client-ID", this._extClientId); request.Headers.Add("Authorization", BEARER_PREFIX + this.MakePubSubToken(channelId, true)); var body = new Dictionary<string, object> { { "content_type", "application/json" }, { "message", message }, { "targets", userIds.Select(uid => $"whisper-{uid}").ToArray() }, }; request.Content = new StringContent( new JsonNetSerializer().Serialize(body), Encoding.UTF8, "application/json"); using var client = new HttpClient(); using var response = await client.SendAsync(request); } private string MakePubSubToken(string channelId, bool isWhisper) { var perms = new perms { send = new string[] { isWhisper ? "whisper-*" : "*" } }; var payload = new Dictionary<string, object> { { "exp", (DateTimeOffset.Now.ToUnixTimeSeconds() + 60) }, { "user_id", this._extOwnerId }, { "role", "external" }, { "channel_id", channelId }, { "pubsub_perms", perms } }; IJwtAlgorithm algorithm = new HMACSHA256Algorithm(); IJsonSerializer serializer = new JsonNetSerializer(); IBase64UrlEncoder urlEncoder = new JwtBase64UrlEncoder(); IJwtEncoder encoder = new JwtEncoder(algorithm, serializer, urlEncoder); var token = encoder.Encode(payload, Convert.FromBase64String(this._extSecret)); return token; } ``` **Expected behavior** Extensions running in the Developer Rig should receive PubSub broadcast events for any topic/target. **Additional context or questions** The example code above DOES work as expected for all topics/targets when running the extension as a Hosted Test in Twitch. In either case the response from the PubSub Broadcast endpoint is `204 No Content`.
