GEE into Mattermost

[MrC2D]

Hello! So I'm not the greatest programmer or software developer, however I thought it would be cool to add a GIS function to Mattermost. I grabbed the Earthenterprise from github and setup the fusion and earth server on a separate VM and I have communications between my host machine and the VM, however when I try to upload the plugin the only error I get is failed to fetch on mattermost?
