Cannot pass in parameters for insertMany mutations in Data Connect

[mickeywu]

[REQUIRED] Environment info

firebase-tools: 14.12.0

Platform: Ubuntu

[REQUIRED] Test case

Firebase Data Connect supports batch operations such as _insertMany and _upsertMany.

However, it doesn't appear to be possible to utilize them in a mutation.

Given the following simple schema with one table:

type Actor @table {
  name: String!
}

If I want to dynamically batch create Actors by passing in an array of Actor data, the following fails:

mutation CreateActors($actors: [Actor_Data!]!) @auth(level: PUBLIC) {
  actor_upsertMany(data: $actors)
}

The Data Connect extension throws and error and manually running firebase dataconnect:sdk:generate will also not generated the appropriate SDKs:

On $actors: cannot use Actor_Data as a variable (please use one variable for each field instead, ex: `{foo: $foo}`)Firebase Data Connect: Compiler

[REQUIRED] Steps to reproduce

Create the test schema outlined above and observe the errors.

[REQUIRED] Expected behavior

Mutations allow passing in data objects as parameters and using them in _insertMany / _upsertMany operations.

Firebase documentation has examples of bulk seeding data, but it is with static data only.

[REQUIRED] Actual behavior

Developer defined mutations cannot dynamically batch insert or upsert using parameters passed into the mutation.
