Heatmap javascript have some error #131

gwontaeyong · 2018-07-23T12:04:12Z

I run kerberosio in docker and i have my config_files.
to start kerberos io_docker_image in my config i'm mount that config_files into /etc/opt/kerberos/config in container
kerberos working well saving image, and show up many graphs except onething heatmap
when i click the heatmap button. the console show up the erro message like that

"Heat.js?bust=20170127:329 Uncaught DOMException: Failed to execute 'drawImage' on 'CanvasRenderingContext2D': The image argument is a canvas element with a width or height of 0."

If i run kerberos_docker_image without mount. all the funtion working well..
What i was know is there is no value related with heatmap in config_files.

Is there anything configuration ?? with heatmap?

Thank you

In FireFox I get the following error:

InvalidStateError: An attempt was made to use an object that is not, or is no longer, usable Heat.js:9

In Chrome, it's slightly different:
