Error in generating PDF for Grafana flowcharting

Hi all,

I am using plugin panel called Grafana Flowcharting which integrate with I decided to use Grafana Flowcharting for my Home Dashboard for monitoring the Server Availability as it can be configured color which indicate the thresholds. Picture as below:

For the PDF configuration, I am using Grafana Reporter using TexLive-PDF. I am having a problem when I wanted to generate PDF for the Flowcharting panel, the result returned error. Picture as below:

I am not sure whether the TexLive is unable to render the image from Flowcharting panel. I have tried generating PDF for another panel which does not have the Flowcharting panel & it’s works fine.

Does anyone know the issue? Really appreciate any helps from you guys.
