(CompileError) 无效的引用表达式

Question

我正在尝试将 elixir 从 1.7 升级到 1.13 以及一些依赖项。我逐渐增加了版本以达到这一点。

方面的任何重大变化

related question。不过，他们给出的示例并不适合初学者。

== Compilation error in file lib/ellie_web/graphql/types/elm/docs.ex ==
** (CompileError) lib/ellie_web/graphql/types/elm/docs.ex: invalid quoted expression: %Absinthe.Blueprint.TypeReference.NonNull{errors: [], of_type: %Absinthe.Blueprint.TypeReference.List{errors: [], of_type: %Absinthe.Blueprint.TypeReference.NonNull{errors: [], of_type: {:type, [line: 4], nil}}}}

Please make sure your quoted expressions are made of valid AST nodes. If you would like to introduce a value into the AST, such as a four-element tuple or a map, make sure to call Macro.escape/1 before

        }
    }
}

尝试次数：

[1]

  scalar :elm_docs_type, name: "ElmDocsType" do
    serialize fn string -> string end

    parse fn
      %Absinthe.Blueprint.Input.String{value: value} -> {:ok, value}
      %Absinthe.Blueprint.Input.Null{}               -> {:ok, nil}
      _                                              -> :error
    end
  end

[2]


  scalar :elm_docs_type, name: "ElmDocsType" do
    serialize(&encode/1) 
    parse(&decode/1)
  end
  @spec decode(Absinthe.Blueprint.Input.String.t()) :: {:ok, term()} | :error
  @spec decode(Absinthe.Blueprint.Input.Null.t()) :: {:ok, nil}
  defp decode(%Absinthe.Blueprint.Input.String{value: value}) do
    {:ok, value}
  end

  defp decode(%Absinthe.Blueprint.Input.Null{}) do
    {:ok, nil}
  end

  defp decode(_) do
    :error
  end

  defp encode(value) do
    value
  end

    ]
  end

Answer 1

这个差异成功了。 defp

似乎有问题

-  defp good_list(type), do: non_null(list_of(non_null(type)))
-
   object :elm_docs_module do
     field :name, non_null(:string)
     field :comment, non_null(:string)
-    field :unions, good_list(:elm_docs_union)
-    field :aliases, good_list(:elm_docs_alias)
-    field :values, good_list(:elm_docs_value)
-    field :binops, good_list(:elm_docs_binop)
+    field :unions, non_null(list_of(non_null(:elm_docs_union)))
+    field :aliases, non_null(list_of(non_null(:elm_docs_alias)))
+    field :values, non_null(list_of(non_null(:elm_docs_value)))
+    field :binops, non_null(list_of(non_null(:elm_docs_binop)))
   end
