[tatdat (Dat Pham Tat)]

Im using Elastic stack 6.2.2.
I setup canvas follow guide from this site http://canvas.elastic.co/stories/installing.html
But this package have version 6.2.3 so i changed version in pakage.json (from 6.2.3 to 6.2.2) and installed success.
When i open canvas in kibana i got error blank page.

How can i fix error.

Thanks!

Looks like you might have hit a build error. When you installed the plugin, did it complete successfully? You can force a re-build by removing the optimize path in the root of Kibana and starting it up again. Give that a shot, and pay attention to the output.
