Thanks @bratsos For your response.
I have hard coded it as my application is in staging environment. Also i have seen that Shopify only provide the host in the first initial load only and later we have to save it in the database and retreivef from there right ?
Because currently i have the host paramter in my iframe url but when i debug it with console.log i get null values.
However one thing is clear that even if i hard code it, it is the same i get for my this store.
So the app should not get broken here.
My Dynamic Code : https://prnt.sc/SXQt8QGmUH2i
Null Output : https://prnt.sc/Jhb8M0kT1B16
However my hard-coded host is right for this store : https://prnt.sc/fFb3u3KDNbce
Please check on this and let me know, I am in talk with various other develoeprs and we are all stuck. If you check this github post, various Shopify partners are facing this issue.
