【问题描述】：

尝试测试我的 Firebase 云功能。我已按照文档进行操作，但在运行测试时出现以下错误。我尝试生成不同的密钥，我通过 Firebase 进入服务密钥窗口，所以它是正确的项目。运行测试时出现错误：npm test

const myFunctions = require('./index.js');

嗨@AlexTaylor，您能否为您的案例添加更多详细信息？如果您可以提供文档和您开始面临错误的确切步骤、有关您的 Firestore 数据库的更多信息等，将有助于社区更好地了解您的案例。

【解决方案1】：

上面写着无效的键“_fieldProto”，如果你看一下这个字典实际包含什么：

"fieldsProto":{"foo":{"stringValue":"bar"}}

我认为您只需要删除传递给包装函数的参数即可。

const wrapped = test.wrap(myFunctions.testFunction);
wrapped(); 
test.cleanup();
