Plugins not working in Grafana Docker

Hello
When I install the FlowCharting plugin of Grafana-pie chart plugin I can see them in the plugin overview. The problem is that I get a message saying “Error Loading Plugin”.

When I look into the browser I see that some files cannot be loaded
When I look into the docker logs I can see this

I am using docker with volume mapping and a custom ini file.
[live]
allowed_origins= *
[users]
default_theme=light
I have a feeling that the custom ini file is not loaded but my docker startup command is the following

docker run -d -p 3000:3000 --name=grafana -v d:\temp\grafana-storage:/var/lib/grafana grafana/grafana d:\temp\grafana-logs:/var/log/grafana d:/temp/grafana-config.custom.ini:/etc/grafana/grafana.ini

Any ideas?
