Flutter Firebase cloud_functions 包抛出错误：INTERNAL

Question

当尝试调用云函数时，我收到“CloudFunctionsException”

• 异常的代码是“INTERNAL
• 该消息是“响应不是有效的 JSON 对象。”

描述错误

重现 重现行为的步骤： - 我来自应用程序的调用是

 HttpsCallable _getName;

 _getName = CloudFunctions.instance.getHttpsCallable(functionName: 'getName',);


 try {
      HttpsCallableResult resp = await _getName.call(<String, dynamic>{'name': name,});
      Scaffold.of(context).showSnackBar(SnackBar(content: Text("${resp.data}")));
    } on CloudFunctionsException catch  (e) {
      showErrorMessage(context, 'Cloud functions exception with code: ${e.code}, and Details: ${e.details}, with message: ${e.message} ');
    } catch (e) {
      showErrorMessage(context, e.toString());
    }

• 我的云函数是这样写的：

exports.getName = functions.https.onCall((data, context) => {
    return {
        "data" : "You hit the call at least!"
    };
});

预期行为 在我的响应中，我应该返回数据：“您拨打了测试电话”。相反，我收到错误

附加上下文 当我使用 HTTP 包调用相同的函数并使用“onRequest”在后端接收它时，它可以工作。

exports.getName = functions.https.onCall((data, context) => {
    return {
        "data" : "You hit the call at least!"
    };
});

exports.getName = functions.https.onRequest((request, response) => {

    const name = request.query.name || request.body.name;
    switch (name) {
        case 'Andrew':
            request.query.name ? response.send("Na he is the boi Q!") : response.send("Na he is the boi B!");
            break;

        case 'Brett':
            request.query.name ? response.send("Na just wierd! Q") : response.send("Na just wierd! B");
            break;

        case 'Eddie':
            request.query.name ? response.send("My brother but yeah! Q") : response.send("My brother but yeah! B");
            break;

        case 'James':
            request.query.name ? response.send("The biggest! Q") : response.send("The biggest! B");
            break;

        default:
            request.query.name ? response.send("Dunno who that is! Q") : response.send("Dunno who that is! B");
            break;
    }
});

就我而言，云函数位于未在索引文件中导出的文件中。确保您的函数已正确导出并已正确部署。
