Dashboard: An unexpected error happened

Grafana 6.7.3
RHEL 7

Trying to push dashboards using grafanalib python library.

When i am pushing dashboard using Grafanalib APIs. Dashboards is created and panels are created inside the dashboard if i use grafana 9.x. Same code i am using to push dashboard in case of grafana 6.6.3 but it shows unexpected error.

Require community help to get exactly what is going wrong.

I would recommend you do not use this ancient version of grafana no longer supported. Any reaaon you cannot migrate?

Also that grafanalib is not a grafana product so you might get better responses if you posted your issues on theit github.

Also please post what you have done in your script?
