Custom type does not exist for Hasura Action

Versions

hasura version
INFO hasura cli                                    version=v2.6.0

Repro

I'm trying to create the following query:

type Query {
  distanceMatrix (arg1: DistanceMatrixInput): MatrixOutput
}

With the following Input type:

# Declare New Types
input DistanceMatrixInput {
  origins: [LatLng]
  destinations: [LatLng]
}

These global types already exist:

# Declared Global Types
type LatLng {
  lat: Float!
  lng: Float!
}

type MatrixOutput {
  rows: [MatrixElementsRow!]
}

type MatrixElementsRow {
  elements: [MatrixElement!]
}

type MatrixElement {
  status: String
  duration: Int!
  durationInTraffic: Int
  distance: Int!
}

Error

This fails, complaining that LatLng does not exist 🤯

"reason": "Inconsistent object: validation for the given custom types failed for the following reasons:\n • the type \"LatLng\" for field \"origins\" in input object type \"DistanceMatrixInput\" does not exist\n • the type \"LatLng\" for field \"destinations\" in input object type \"DistanceMatrixInput\" does not exist\n"

Why?

Why would it say LatLng does not exist when I have a LatLng type in actions.graphql?

Temporary Solution

Temporarily, I can switch to something like:

input DistanceMatrixInput {
  originLats: [Float!]!
  originLngs: [Float!]!
  destinationLats: [Float!]!
  destinationLngs: [Float!]!
}

But this isn't ideal.

Hello @kevinmichaelchen,

Maybe a little bit late, but the solution is to use input nesting in your case.

input LatLng {
  lat: Float!
  lng: Float!
}

input DistanceMatrixInput {
  origins: [LatLng]
  destinations: [LatLng]
}

And of course, don't forget to declare LatLng as an input in your actions.yaml.

Cheers.
