Shopify app proxy returns 302 status code and redirect /auth/login

[devgiri0082]

I have a shopify app proxy so that I can get data from my db and populate it in the app theme extension.  Below is my liquid  file and proxy file. Everything works good, the console.log is printed when I call the function but in the frontend I keep getting  the below response:
