Javascript Firebase功能测试初始化失败

正在尝试测试我的Firebase云功能。我遵循了文档，在运行测试时出现了以下错误。我尝试过生成不同的密钥，我通过Firebase访问服务密钥窗口，因此它是正确的项目。运行测试时出错：

npm测试

const test = require('firebase-functions-test')({
     databaseURL: "####",
     storageBucket: "####",
     projectId: "#####",   }, './key.json');
 
 
const myFunctions = require('./index.js');
 
const wrapped = test.wrap(myFunctions.testFunction);
const snap = test.firestore.makeDocumentSnapshot({foo: 'bar'}, 'document/path'); 
wrapped(snap); 
test.cleanup();

它说的是无效的密钥“_fieldProto”，如果你看一下这个dict实际上包含的内容：

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

我认为您只需要删除传递到包装函数中的参数

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

你好，AlexTaylor你能为你的案子添加更多细节吗？如果您能够提供文档和您开始面对错误的确切步骤，有关Firestore数据库等的更多信息将有助于社区更好地了解您的案例。

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