I’m encountering a problem when trying to access fields from the response of the apiQuery function. Specifically, when I try to access a field like response.data.editMeteringpointMutation.address, TypeScript raises an error saying Property ‘address’ does not exist on type, and I don’t see any other fields either.

Here’s how I call the function:

let response = await apiQuery('editMeteringpointMutation', {
  ...props.meteringpoint,
  metering_point_id: props.meteringpoint.id,
});

However, when I call it with additional parameters as follows:

let response = await apiQuery(
  'editMeteringpointMutation',
  {
    ...props.meteringpoint,
    metering_point_id: props.meteringpoint.id,
  },
  ['address'],
  true
);

Everything works fine. It also works correctly when I pass an array without the allow parameter, where it omits my address.

Why is my object empty when I don’t pass the fields or allow parameters?
Why do I expect it to be populated but it’s not?

The problem lies on Q i guess

type NestedPick<T, K extends keyof any> = {
  [P in keyof T]: Pick<T[P], Extract<K, keyof T[P]>>
};

type NestedOmit<T, K extends keyof any> = {
  [P in keyof T]: Omit<T[P], Extract<K, keyof T[P]>>
};

export const apiQuery = async <
  T extends keyof typeof mutations | keyof typeof queries,
  Allow extends boolean = false,
  V = T extends keyof typeof mutations
    ? (typeof mutations)[T]['__generatedMutationInput']
    : T extends keyof typeof queries
    ? (typeof queries)[T]['__generatedQueryInput']
    : never,
  R = T extends keyof typeof mutations
    ? (typeof mutations)[T]['__generatedMutationOutput']
    : T extends keyof typeof queries
    ? (typeof queries)[T]['__generatedQueryOutput']
    : never,
  P = T extends keyof typeof mutations
    ? (typeof mutations)[T]['__generatedMutationOutput'][keyof (typeof mutations)[T]['__generatedMutationOutput']]
    : T extends keyof typeof queries
    ? (typeof queries)[T]['__generatedQueryOutput'][keyof (typeof queries)[T]['__generatedQueryOutput']]
    : never,
  K extends keyof P = keyof P,
  Q = [K] extends [never]
    ? R
    : Allow extends true
    ? NestedPick<R, K>
    : NestedOmit<R, K>
>(
  queryString: T,
  variables: V,
  fields?: K[],
  allow?: Allow,
  authMode?: GraphQLOptions['authMode']
) => {
  // Function implementation
}
