Description

I am encountering a “Not Authorized to access **** on type Query” error while attempting to enable guest access (using allow.guest()) for a custom query in Amplify Gen 2. The same setup works correctly when I switch to allow.authenticated(), and everything functions as expected if the user is signed in. However, as soon as I revert to allowing guest access for the query (so that unauthenticated users can retrieve SubscriptionProduct and OneTimeProduct data), the API call consistently fails with the “Not Authorized” error. This issue persists despite closely following the Amplify documentation and properly configuring the custom types and query handler.

        SubscriptionProduct: a.customType({
            id: a.string(),
            name: a.string(),
            description: a.string()
        }),

        OneTimeProduct: a.customType({
            id: a.string(),
            name: a.string(),
            description: a.string(),
            price: a.float()
        }),

        GetProducts: a
            .query()
            .returns(
                a.customType({
                    subscriptionProducts: a.ref('SubscriptionProduct').array(),
                    oneTimeProducts: a.ref('OneTimeProduct').array(),
                })
            )
            .handler(a.handler.function(getProducts))
            .authorization((allow) => allow.guest()),
