Frappe Insights with with Frappe v15 installation showing error

I’ve installed Insights with the new Frappe 15 and Erpnext 15. Installation was smooth but when i try to connect to data source it’s showing error.
When I try to load the sample dataset it gets stuck on loading (the contiune buttons is disabled), it creates the local csv and sqllite files but it’s stuck. When i try to connect to erpnext it won’t contiune to the dashboard. Its throwing the error below on the console.
