Can you hit https://pasta223.myshopify.com/tools/aswin-app-223/json once and confirm that in your repo /pages/api/proxy_route/json exits? You'd be getting a 404 because there's no /pages/api/proxy_route/index.js to serve that request

now it's working when i hit https://pasta223.myshopify.com/tools/aswin-app-223/json this URL, but

https://pasta223.myshopify.com/tools/aswin-app-223 this url not working but i have index.js handler in proxy_route i dont know why this happening newbie here can you tell me why?.

If it's working when you hit /json, that means it's working as expected. Just add in your routes and you're good to go. I'm not sure why proxy_route/index.js wouldn't work by default, which is odd since the other route is working. I would just add other routes and work on that instead.
