Compile-time error: "Argument field or value named 'order_by' can not be coerced"

使用查询和 schema 片段作为最小复现；首先跟踪 GraphQL 类型提供程序如何强制转换输入对象字段，尤其是枚举值的 order_by 和 distinct_on 字段。完成的标准是示例能够编译，并产生与手动运行的查询相同的结果，同时覆盖这些情况。

Description

I am using Hasura, and trying to run the following query:

let operation = MyProvider.Operation<"""query q {
      test_table (order_by: {some_name: asc}) {
        id
        some_name
      }
    }""">

The query is valid and works if run manually, but I get a compile-time error with the F# Type Provider:

error FS3033: The type provider 'FSharp.Data.GraphQL.Client.GraphQLTypeProvider'
reported an error:
Argument field or value named 'order_by' can not be coerced.
It does not match a valid literal representation for the type.
Path: ["q"; "test_table"]

The relevant part of the schema:

{
  "inputFields": null,
  "kind": "ENUM",
  "possibleTypes": null,
  "interfaces": null,
  "name": "order_by",
  "enumValues": [
    {
      "isDeprecated": false,
      "deprecationReason": null,
      "name": "asc",
      "description": "in the ascending order, nulls last"
    },
  ...
  ],
  "description": "column ordering options",
  "fields": null
}

I've tried other parameters, such as offset, limit, where (this one works now: https://github.com/fsprojects/FSharp.Data.GraphQL/issues/263), and they work. distinct_on, however, results in the same compile time error. Could this have something to do with the _ in the name?

Repro steps

See description.

Expected behavior

The application compiles, the query returns the same result as when run manually.

Actual behavior

Compile-time error.

Known workarounds

None.
