Building a react-admin data provider for FaunaDB - react-admin

Question

With Graphcool being sunsetted, I've been trying to get react-admin to work with Fauna, but have not been successful. The Fauna GraphQL grammar is different than Graphcool, and of course when I connect to my Fauna DB, it doesn't recognize any of the resources.
If I build a very simple Fauna DB by uploading the following GraphQL schema:
type Location {
name: String!
address1: String!
address2: String
city: String
state: String
zip: String
}
type Query {
allLocations: [ Location ]
}
The final schema that Fauna creates looks like:
directive #embedded on OBJECT
directive #collection(name: String!) on OBJECT
directive #index(name: String!) on FIELD_DEFINITION
directive #resolver(
name: String
paginated: Boolean! = false
) on FIELD_DEFINITION
directive #relation(name: String) on FIELD_DEFINITION
directive #unique(index: String) on FIELD_DEFINITION
scalar Date
type Location {
city: String
name: String!
zip: String
state: String
_id: ID!
address2: String
address1: String!
_ts: Long!
}
input LocationInput {
name: String!
address1: String!
address2: String
city: String
state: String
zip: String
}
type LocationPage {
data: [Location]!
after: String
before: String
}
scalar Long
type Mutation {
createLocation(data: LocationInput!): Location!
updateLocation(
id: ID!
data: LocationInput!
): Location
deleteLocation(id: ID!): Location
}
type Query {
findLocationByID(id: ID!): Location
allLocations(
_size: Int
_cursor: String
): LocationPage!
}
scalar Time
I'm having a hard time figuring out how to adapt the Graphcool/GraphQL data providers to account for the difference in the Fauna grammar. A couple of differences I've noticed:
Fauna names the IDs _id, but ra-data-graphcool expects them to be id
Fauna create/update mutations expect a single input object that mirrors the type
There are probably also differences in how the Graphcool data provider builds out the gql for getting record lists as well. Has anyone created or modified a data provider for Fauna (or maybe Back4App or other free/inexpensive cloud GraphQL providers)?
