All other json viewers work for a few pages I tested except this one.

It does work for the demo site you list though.

I am getting this error in the console from your plugin, tested by disabling the plugin the error disappears, on re-enabling it re-appears.

Error handling response: TypeError: Cannot read properties of null (reading 'request')
