Http request to mqtt doesn't pass the content? manually injecton works!

Developing Nodes

Hey node-red´ers

  • A esp32 with an OLED sends every 10 sec to a MQTT Topic a message.
  • Than my website generates data and makes a JSON.
  • This json should send to MQTT OUT .

The part at the bottom works. So my ESP are getting the Data which are manually injected.
I'm also seeing the JSON in debug 7
The HTTP Request works - but the data won't send to the matrixDaten Topic

What do I miss here? Any suggestions?
Thanks

My guess would be that you are using a subtly different topic for the two mqtt out nodes.

Of course it is only a guess because you haven't shown us either the JSON for your flow or the data.

Suggestion: add an mqtt in node to monitor all topics (#) and connect it to a debug node.

As well as showing us what is in the message to the mqtt nodes, feed the lower inject into the top mqtt node to check the problem is not there.

Thanks for your replys. It helped me, because so I know that my flow was not complete a mess :slight_smile:

I changed the URL from the HTTP Request to: https://jsonplaceholder.typicode.com/todos/1 - with this test url my flow works. Although my JSON is valid, I have to investigate once more.

Greetings
