How can I recover a json message from a distant server?

[chris35]

to go further I would like to use the node switch to send the message in a direction according to the value of sensorInstallId
is it a good idea ?
I've read Switch node - jsonata - magic?
but I don't understand if the "Key is" exist or not ?

for the moment I've made this

but the property 1 doesn't match .... it's the otherwise property(6) which send a debug message
What's wrong in my reflexion ?

Thanks
