It's me or Storefront GraphQL API are not mature for production?

today i run in a weird bug or whatever … actually i’m not able yet to identify the reason

on dev store i get null or empty array whatever query i run on product / collections

for instance:

query {product(handle:"product-handle") {id}} 

return:

{
    "data": {
        "product": null
    }
}

while fetching https://mytore.myshopify.com/products/product-handle.json work fine

the same for:
query {collection(handle:"collection-handle") {id}}
and
https://mytore.myshopify.com/collections/collection-handle.json

so my question is … i’m just doing something wrong like GQL have some hidden cap that rest does not have or i should keep using rest api because GQL it’s not stable yet?

ok recreate the storefront token worked for me :exploding_head:

but i still have the same question … are Storefront GQL API stable or weird stuff like this may happen again?
