Hello guys! So we're trying to READ the KEPSERVER using NODE-RED.  
So my problem is that the NODE-RED CAN'T READ THE DATA FROM THE KEPSERVER... As you can see in the attached photo, the Debug Node reads only the Inject Node and not the data from the kepserver...

Thank you so much!  
btw I am using

`node-red-contrib-opcua`

here is my flow:
