Panels rendering timeout

[Teajo]

Hello everyone,

I experienced some troubles with grafana image renderer (same troubles with PhantomJS renderer).
Some panels (like Clock, DrawIO, and some of my custom panels) are impossible to render (the timeout is always reached).

Some logs :
lvl=eror msg="Render request failed" logger=rendering url="http://localhost:3000/d-solo/ksSgva0Wz/main?orgId=1&from=1572495407183&to=1572500826087&panelId=27&width=1000&height=500&tz=Europe%2FParis&render=1" error=map[name:TimeoutError] timestamp=0001-01-01T00:00:00.000Z

Environment :

• Grafana Image Renderer version : 1.0.7
• Grafana version : 6.4.3
• Installed plugin or remote renderer service : installed plugin
• OS Grafana Image Renderer is installed on: Debian 9
• User OS & Browser: Windows, Chrome

Do you know how can I fix that ?

Thanks

Sorry I have updated my message with informations you need ! Thanks

• Does it work to render graph panel?
• Would suggest trying an older version of the plugin, like 1.0.5 to start with - does that work?
• In case above doesn't work, can you include a Grafana dashboard json having one of the panels that you're having problems to render, please leave out any sensitive information.

Thanks

• Yes it works correctly with graph panel
• Tested with 1.0.5 and same troubles
• The file is here dashboard.txt. It contains a dashboard json with an unique flowcharting panel.

Thanks

Confirmed bug. Could be a bug in flowchart panel

Think this.renderingCompleted() needs to be called here and/or when render is finished: https://github.com/algenty/grafana-flowcharting/blob/master/src/flowchart_ctrl.js#L71

Would suggest to open an issue in https://github.com/algenty/grafana-flowcharting
