The unexpected token message probable comes from the json node telling you the data sent to it is bad. Add a debug node (set to display the complete msg object) to the the output of the http to show what it is getting.
Looking at the url from the screenshot you shared it seems that you are using a self signed certificate ?
The following from the http request nodes Help tab :
so set in your Http request node the url to be https:// ... (in the first screenshot you had it http)
and also the above option msg.rejectUnauthorized = false (set from the Inject node)
that must be for the msg.topic field that you have not set correctly and its highlighted in red.
just press X to remove the topic row (or fill it with a valid value if you need to)
