I have a doubt with fragmentReplacements.

I am testing the graphql shield with Yoga using UrlLoader from a remote GraphQl server.

const hasFieldPermission = rule({
  cache: 'strict',
  fragment: `    
     fragment navigationMainAccessRestrictionFrag on NavigationMain {
            brands
            locations
            channels
        }
     }
`,
})(async (parent, args, { ctx }, info) => {
//   const { brands, locations, channels } = parent
  console.log('ACCESS', parent)
  //... do some thing

  return false
})

The parent is always undefined.

I think that I need do something with fragmentReplacements but I don't find any documentation about that.

Hi,

I managed to make it work,

The problem is that I added hasFieldPermission on Query.navigationMains.

But when I added the on type NavigationMain the parent gets populated.

const hasFieldPermission = rule({
  cache: 'strict',
  fragment: `    
     fragment navigationMainAccessRestrictionFrag on NavigationMain {
        accessRestrictions {
            brands
            locations
            channels
        }
     }
`,
})(async (parent, args, { ctx }, info) => {
//   const { brands, locations, channels } = parent
  console.log('ACCESS', parent)

  return true // && (parent || true)
})

export const permissions = shield({
  Query: {
    navigationMains: hasFieldPermission, // NOT works
  },

  NavigationMain: {
    '*': hasFieldPermission,  // it works when I added this
  },
