I am developing a shopify application using NodeJs and using libraries koa-shopify-auth, koa, next.

If i will install the app <>/auth?shop=<shop> its working fine its redirecting with session cookie set, but if i install the app with url ->

https://<><client_id>&scope=read_orders,read_products... after accepting the permission the app returning internal server app - 

InternalServerError: Cannot complete OAuth process. Could not find an OAuth cookie for shop url: <>

and look like QA team is installing the app using that link. can anyone help me what could be reason that error is coming?
