In your second image, the debug node is covering some of the message and the message is off the screen. If you look in the node-red log, you should see the full msg. Copy and paste it to a response.
In addition, when you have a problem you should provide background information.
- What version of node-red and node.js are you running (you can get this from the start up log)
- what OS and device are you running node read on
- an export of your flow
In order to make code readable and usable it is necessary to surround your code with three backticks (also known as a left quote or backquote ```)

I recommend watching this playlist: Node-RED Essentials. The videos are done by the developers of node-red. They're nice & short and to the point. You will understand a whole lot more in about 1 hour. A small investment for a lot of gain.
