Hi @ChandanDreamz ,

Thanks for your post. When testing the query and variables you provided in both a recent version of Postman as well as Insomnia in a test store using variant id’s from the test store it’s working normally.

This indicates the problem is something relating to local usage of the app or it’s settings which is beyond our direct scope of support so perhaps the community will have further ideas.

Hope you have a great day,

I am also facing the same issue “CartInput is not a valid type” but according to the documentation CartInput is a valid type.
