I am trying to learn magento admin grid creation. So I created model/collections, UI_component,di.xml, layout xml etc. But I always get the admin loader spinning (screen shot attached). I feel that it's a issue with data fetching through collection. Can anyone help me in this as the documentation for UI is little tough to understand for a beginner like me.
I have provided the code in a github. https://github.com/sathyashrayan/magento2_practice
Thanks for any help.
