IoT gateway data to MQTT and then to KAFKA

General

Welcome to the forum!

While I'd love to give you an answer, you haven't given much to go on. Do you realize there are 15 nodes with KAFKA in the name?

When your looking for help it's a good idea to remember the person answering your question has no idea what type of device your node-red is running on, what version you are using, what nodes you are using, what the error you are getting and might not even know what Kafka is (which is true in my case).

So (incase someone else can help you ) please answer the following

  1. what version of Node-RED and node.js are you using (see the startup log)
  2. what Kafka node are you using (full name i.e. node-red-contrib-?????)
  3. what device is NR running on? What os?
  4. what error are you seeing?
  5. where is the Kafka API documentation?
  6. are you accessing an external Kafka service?

And it might be helpful to provide your flow. (in order to make code more readable and importable it is important to surround your code with three backticks
```
like this
```

You can edit and correct your post by clicking the pencil icon.

See this post for more details - How to share code or flow json)

You might want to put a catch node connected to a debug node (set to display the complete msg object) on the tab with your flow, it might provide more information.

Hopefully with all that someone will be able to guide you to a solution.
