GraphQL错误字段类型必须是输入类型,但得到: [英] GraphQL Error field type must be Input Type but got:
本文介绍了GraphQL错误字段类型必须是输入类型,但得到:的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
这是突变:
const createNotebook = mutationWithClientMutationId ({
name: 'CreateNotebook',
inputFields: {
token: {
type: GraphQLString,
},
details: {
type: NotebookDetails,
},
},
outputFields: {
},
async mutateCRNotebook(input, context) {
const data = getJSONFromRelativeURL(input.token);
},
});
以下是变异详细信息字段中使用的模式:
Here is the schema used in the details field of the mutation:
const NotebookDetails = new GraphQLObjectType({
name: 'NotebookDetails',
interfaces: [nodeInterface],
fields: () => ({
id: globalIdField('NotebookDetails'),
description: {
type: GraphQLString,
description: '...',
resolve(obj) {
return obj.description;
},
},
language: {
type: GraphQLString,
description: '...',
resolve(obj) {
return obj.language;
},
},
}),
});
我在运行此代码时出错:
Error I am getting on running this code is :
api_1 | Error: CreateNotebookInput.details field type must be Input Type but got: NotebookDetails.

我用过这种语法与查询和他们正常工作。但是,他们正在返回带有突变的错误。
我的代码中有什么不正确以及如何更正?
I have used this syntax with queries and they worked correctly. But, they are returning error with a mutation. What is incorrect in my code and how do I correct it?
推荐答案
在GraphQL中,输入
不能用作类型
而类型
不能用作输入
。不幸的是,即使结构与现有类型相同,您也必须定义一个单独的输入以用作参数。尝试这样的事情:
In GraphQL, an input
cannot be used as a type
and a type
cannot be used as an input
. Unfortunately, even if the structure is identical to an existing type, you always have to define a separate input to use as an argument. Try something like this:
const NotebookDetailsInput = new GraphQLInputObjectType({
name: 'NotebookDetailsInput',
fields: () => ({
id: { type: GraphQLID },
description: { type: GraphQLString },
language: { type: GraphQLString },
})
});
