One more thing now:
I’ve found this post here which is very similar to my problem. So I definitely tried this out. But I have another plugin having an issue with that - the mattermost plugin. This plugin needs the “generic-host” and “user” from the templates.conf so I included that conf too but I get a lot more errors then. Basically does the mattermost plugin need the entire templates conf. I’m not sure how or where I should replicate it in the director so that the plugin can find it.
