created new dashboard with "413 Request Entity Too Large“

Hi everyone,

Good day. version is :1.17.1.

I follow the blog : https://www.percona.com/blog/2017/02/02/pmm-alerting-with-grafana-working-with-templated-dashboards/ to create a new dashboard. However, when I save the dashboard, I got “413 Request Entity Too Large” error. Please check attached screenshot and panel JSON.

I appreciated for your advise.

Thanks,
Dillon
