Pie plugin usage issue

I have installed pie plugin in grafana.

When i am trying to use it i am getting the below error.

Please suggest me to resolve this issue.

Check your log file. if you enabled logs. Open plugin folder and see that are you able to see the plugin in folder and then see plugin in installed plugin list of dashboard

I am able to see plugin in the installed plugin list.

I am getting able error, only if i am using the pie chart plugin.

And also i didn’t find anything in grafana logs

Have you change the log file level in custom.ini?

I have set the log level to debug in custom.ini
