找不到文件：/_ah/start on Google App Engine

Question

我最近在我的 GAE 本地应用程序上从默认缩放更改为手动缩放。我可以从 /api/* 路径获得响应，但我的欢迎文件不再有效。

我明白了

Problem accessing /. Reason:

Forbidden

并且在启动服务器时显示：

com.google.appengine.tools.development.jetty9.LocalResourceFileServlet doGet

WARNING: No file found for: /_ah/start

在此之前一切正常，这是我的 appengine-web.xml

<?xml version="1.0" encoding="utf-8"?>
<appengine-web-app xmlns="http://appengine.google.com/ns/1.0">
    <version>1.0</version>
    <manual-scaling>
        <instances>1</instances>
    </manual-scaling>
    <instance-class>B1</instance-class>
    <threadsafe>true</threadsafe>
    <sessions-enabled>true</sessions-enabled>
    <runtime>java8</runtime>
        <static-files>
            <include path="/**.html"></include>
            </static-files>
    <resource-files>
        <include path="/**.json" />
    </resource-files>
</appengine-web-app>

和我的web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" version="3.1">

    <filter-class>slFilters.restrictFilter</filter-class>

  <session-config>

  </session-config>
    <welcome-file-list>
        <welcome-file>index.html</welcome-file>
    </welcome-file-list>
</web-app>

index.html 是一个简单的 hello world html 文件，应该在访问 localhost:8080

时显示

非常感谢任何帮助

/_ah/start 被击中，因为您选择了手动缩放：

Manual Scaling: Requests can run for up to 24 hours. A manually-scaled instance can choose to handle /_ah/start and execute a program or script for many hours without returning an HTTP response code. Task queue tasks can run up to 24 hours.
