Additional context

Only started crashing recently, it was working fine before. Potentially after upgrade to Mattermost 7.8.6.

[ohemelaar]

To all facing the same issue, I found a fix that I shared in #239 but I don't know Go so I don't think it's the right way. If anyone is willing to review it and suggest something better you're welcome.
