Grafana Image Render Plugin on Pi3 with Buster - Anyone been successful getting it to run

I’m trying to use the Direct link rendered image option in Grafana but can’t get it to work anymore. It was working fine with Openhab 2.4 and an older version of Grafana but an SD card corruption has forced me to update everything.

I have tried various tutorials and options to get this to work but the most recent ones seem to be from around June last year, and don’t quite match my hardware setup. Has anyone had any success getting this to work on a Pi3 using Raspbian Buster, for Openhab 2.5 and Grafana 6.6.1?
