2019-03-22 09:12:44 UTC - Ali Ahmed: not really but some people have looked into building a mqtt gateway for pulsar <https://github.com/HSLdevcom/pulsar-mqtt-gateway> ---- 2019-03-22 16:12:00 UTC - Patrick Johnmeyer: I'm trying to use Pulsar via WebSockets, and I'm having an issue after connection is established. I need help getting more debug information from Pulsar to figure out what is happening. I tried running it like so:
```bash docker run -it \ -e "PULSAR_LOG_LEVEL=debug" \ -p 6650:6650 \ -p 8080:8080 \ -v $PWD/data:/pulsar/data \ apachepulsar/pulsar:2.3.0 \ bin/pulsar standalone ``` But I still only get the following generic `null` WebSocket error. ``` 04:39:29.021 [pulsar-web-55-15] INFO org.apache.pulsar.websocket.AbstractWebSocketHandler - [/172.17.0.1:42562] New WebSocket session on topic <persistent://public/default/fluent-bit> 04:39:39.006 [pulsar-web-55-13] INFO org.apache.pulsar.websocket.AbstractWebSocketHandler - [/172.17.0.1:42562] WebSocket error on topic <persistent://public/default/fluent-bit> : null 04:39:39.007 [pulsar-web-55-13] INFO org.apache.pulsar.websocket.AbstractWebSocketHandler - [/172.17.0.1:42562] Closed WebSocket session on topic <persistent://public/default/fluent-bit>. status: 1006 - reason: Disconnected ``` ---- 2019-03-22 16:19:53 UTC - Grant Wu: @Patrick Johnmeyer Recently began to run into a similar issue ---- 2019-03-22 16:20:01 UTC - Grant Wu: I believe the fix is to use `PING` ---- 2019-03-22 16:20:22 UTC - Grant Wu: Although this might be slightly different ---- 2019-03-22 16:20:27 UTC - Grant Wu: Because my issue had reason 1001 ---- 2019-03-22 16:20:37 UTC - Grant Wu: <https://apache-pulsar.slack.com/archives/C5Z4T36F7/p1553183645832800> ---- 2019-03-22 16:41:34 UTC - Patrick Johnmeyer: I'll try this, thanks. ---- 2019-03-22 16:42:02 UTC - Grant Wu: If this is in node, might be worth moving to <#CFTUA9AHK|dev-node> ---- 2019-03-22 16:42:05 UTC - Patrick Johnmeyer: Yeah, and my "error on topic" is `null` which isn't very helpful. :slightly_smiling_face: ---- 2019-03-22 16:42:09 UTC - Grant Wu: Although maybe there should be a #dev-websocket ? :thinking_face: ----
