javascript - graphqljs - 如何获取文件名和错误行

Question

我正在使用 graphqljs 和 express-graphql。每当我收到错误时，我都会得到一些模糊的信息，例如 "Expected type Int!, found\"1\" with an unhelped location property:

"locations": [
    {
        "line": 3,
        "column": 42
    }
],

如何获取文件名及其行？

以下错误:

"{
    "errors": [
        {
            "json": "{\"message\":\"Expected type Int!, found \\\"1\\\".\",\"locations\":[{\"line\":3,\"column\":42}]}",
            "message": "Expected type Int!, found \"1\".",
            "locations": [
                {
                    "line": 3,
                    "column": 42
                }
            ],
            "stack": [
                "GraphQLError: Expected type Int!, found \"1\".",
                "    at isValidScalar (/Applications/MAMP/htdocs/whylookforit-server/node_modules/graphql/validation/rules/ValuesOfCorrectType.js:164:27)",
                "    at Object.StringValue (/Applications/MAMP/htdocs/whylookforit-server/node_modules/graphql/validation/rules/ValuesOfCorrectType.js:128:14)",
                "    at Object.enter (/Applications/MAMP/htdocs/whylookforit-server/node_modules/graphql/language/visitor.js:333:29)",
                "    at Object.enter (/Applications/MAMP/htdocs/whylookforit-server/node_modules/graphql/language/visitor.js:384:25)",
                "    at visit (/Applications/MAMP/htdocs/whylookforit-server/node_modules/graphql/language/visitor.js:251:26)",
                "    at validate (/Applications/MAMP/htdocs/whylookforit-server/node_modules/graphql/validation/validate.js:63:22)",
                "    at /Applications/MAMP/htdocs/whylookforit-server/node_modules/express-graphql/dist/index.js:154:52",
                "    at processTicksAndRejections (internal/process/next_tick.js:81:5)"
            ]
        }
    ]
}"

所有的 graphql 代码都会被捆绑到一个大模式中，只有在完成之后，coge 才会运行。如果模式运行时出现错误，则代码不再引用最初定义的文件。
