More than just the graph is rendered

What happened:

When i request a rendered version of the graph, i get a PNG of a whole section of the grafana dashboard

What you expected to happen:

To just get a PNG of the graph I requested, without extra graphs and Grafana artwork

How to reproduce it (as minimally and precisely as possible):

We installed the latest versions of Prometheus, Grafana & Grafana Image Renderer. I’m running with default Grafana configuration except for:

[paths]
data         = /srv/shared/grafana/data
logs         = /srv/shared/log/grafana
plugins      = /srv/shared/grafana/plugins
provisioning = /srv/shared/grafana/conf/provisioning
[server]
http_addr           = 127.0.0.1
http_port           = 3000
root_url            = https://vbox1-local-development.transloadit.com/grafana
serve_from_sub_path = true
[dashboards]
default_home_dashboard_path = /srv/shared/grafana/jsondashboards/regional.json
[auth.anonymous]
org_name = Transloadit
[log]
mode = syslog
[log.syslog]
tag = grafana
[external_image_storage]
provider = s3
[external_image_storage.s3]
bucket     = XXX
region     = us-east-1
path       = /grafana/renderings
access_key = XXX
secret_key = XXX

Anything else we need to know?:

Here is an actual PNG that was returned instead of just one graph:

I got this picture by clicking here:

Environment:

• Grafana Image Renderer version: v1.0.0
• Grafana version: Grafana v7.3.6
• Installed plugin or remote renderer service: Remote Renderer Service
• OS Grafana Image Renderer is installed on: Ubuntu
• User OS & Browser: Ubuntu, Firefox

• We’re not using v1.0.0 there, but instead a fairly recent master (ce1f81438e5f69c7fd7c73ce08bab624c4c92e25).
• The issue disappears as soon as we comment out root_url. I confirmed that using http or https doesn’t make a difference. Also, setting and unsetting the hostname from root_url (see above for the config snippet) to 127.0.0.1 in /etc/hosts doesn’t make a difference as well.
• As requested, I ran the service yesterday with more verbose logs enabled: https://gist.github.com/Ma27/51fd65d8a2182c5a0c5e8855d956e2fc

Now I’m not experienced with the internals of how this plugin works. Do those additional things help you to comprehend this issue or is there anything else I can do? 😃

Wow, that fixed it, thank you so much, and sorry for wasting your time over a misconfiguration on our part 👌
