@Matthias_Kamps,

Just so you know, I was able to get to that point with [this documentation](https://arduinojson.org/v6/api/jsondocument/#using-a-jsondocument) from ArduinoJson.

The important part to note here is:

> JsonDocument::to() clears the document and converts it to the specified type. Don’t confuse this function with JsonDocument::as() that returns a reference only if the requested type matches the one in the document.

Happy that we were able to get you sorted out!

Enjoy,  
Heath
