Ryan, please see [Wiki - how to post code on this forum](https://forum.inductiveautomation.com/t/wiki-how-to-post-code-on-this-forum/77831). It limits the length of the code or error block on your post by putting it in a scrollable window. This prevents the posts getting ridiculously long. Can you edit to fix?
