Eden, please see [Wiki - how to post code on this forum](https://forum.inductiveautomation.com/t/wiki-how-to-post-code-on-this-forum/77831). (You've posted your error log as a quotation instead of preformatted text. The preformatted text option limits the length of your post by adding a scroll bar to the text block and keeps the forum tidy.)
