So I finally got everything going and it working well, sorta.
This is what my map looks like when everything works.
This is what it looks like when the issue pops up.
This is what shows up in the log when it happens.

Now to resolve the issue all you have to do is open the graph’s associated with the DS and then the data will show back up in the map. Then 10 mins later it will happen again. I have repeated this several times. I also checked the graph’s and there is no missing data.
This is what is in my conf.

# That's All Folks!
My System is Ubuntu 16.04, PHP 7, Cacti 1.1.6. WeatherMap 0.98a refactor branch.
I wanted to post it here before putting it on GitHub just in case it was just a dumb mistake on my part.
Also another thing to note is the hover over graph’s work flawlessly.
