Poorly described parsing error

[dim-37]

Description

I have a structure

type InputAssignRoleToUser = {
    UserId : ConsoleUserId
    PropertyId : PropertyId
    RoleId : ConsoleUserRoleId
}

and here's its description for graphql

Define.InputObject<InputAssignRoleToUser>("InputAssignRoleToUser",
    [
        Define.Input("userId", ConsoleUserIdType)
        Define.Input("roleId", ConsoleUserRoleIdType)
        Define.Input("propertyId", PropertyIDType)

    ])

here is how the ConsoleUserRoleId ConsoleUserId fields are described

static member ValidStringScalar<'t>(typeName, createValid : Validator<string, 't>, toString : 't -> string, ?description: string) (*: ScalarDefinition<string, 't>*) =
    let createValid : string -> ValidationResult<'t> = createValid typeName
    Define.WrappedScalar
        (name = typeName,
         coerceInput =
            (function
            | Variable e when e.ValueKind = JsonValueKind.String -> e.GetString() |> createValid |> Result.mapError ValidationErrors.toIGQLErrors
            | InlineConstant (StringValue s) ->                                 s |> createValid |> Result.mapError ValidationErrors.toIGQLErrors
            | Variable e -> e.GetDeserializeError typeName
            | InlineConstant value -> value.GetCoerceError typeName),
         coerceOutput =
            (function
            | :? 't as x -> Some (toString x)
            | :? string as s -> s |> Some
            | _ -> raise <| System.NotSupportedException ()),
         ?description = description)

and this is how the PropertyIDType field is described

Define.WrappedScalar
    (name = typeName,
     coerceInput = (function
        | Variable e when e.ValueKind = JsonValueKind.String -> e.GetString() |> PropertyId.ofString |> Ok
        | InlineConstant (StringValue s) ->                                 s |> PropertyId.ofString |> Ok
        | Variable e -> e.GetDeserializeError typeName
        | InlineConstant value -> value.GetCoerceError typeName),
     coerceOutput =
        (function
        | :? PropertyId as x -> Some (PropertyId.toString x)
        | :? string as s -> s |> Some
        | _ -> raise <| System.NotSupportedException ()),
     ?description = Some "I of specific property")

here is the request

mutation {
  administration {
    assignRoleToUser(roleToUser: 
      { 
        propertyId: "c_6740b959-030c-4779-835a-711aaf814f58", 
        roleId: "6740b959-030c-4779-835a-711aaf814f58", 
        userId: "6740b959-030c-4779-835a-711aaf814f58" })
  }
}

and this is the response I'm getting

{
  "documentId": -1969558732,
  "errors": [
    {
      "message": "Index was outside the bounds of the array."
    }
  ]
}

the error occurs somewhere after propertyId conversion but before roleId because the debugger does not enter the conversion to roleId but correctly and without errors exits from propertyId.

Expected behavior

More useful error message

Actual behavior

An error that doesn't tell me anything that can help me.

Known workarounds

Most likely it will help to replace all custom types with standard ones, but it will not solve the problem with bad error message.
