I am querying a Sonos node to get my saved favourite radio stations to send to a dashboard dropdown node. From what I have researched, I should be sending it as a msg.options object.
I have located the parts of where my radio stations are stored.
They are stored in payload[0].title, payload[1].title etc. One of the (many) problems is I do not know how long the array is. I can see a number on the debug node but cannot find a corresponding value in the message. I have experimented with substringafter and substringbefore, that did not work. I also experimented with the split node and the string node. FAIL.
I guess that somehow I have to use a function node to read the array, store it, then send as msg.options
Marked here is the array length (but cannot find that number in the message) and one of the stations I need
This is the whole debug message:

I was properly overthinking this one. Creating problems where there arent any... I didnt think jsonata would parse the whole object.
