我试图让我的测试自动授予带有上限的权限，但总是当我尝试这样做时，我得到了一个 InvalidArgumentError。我该如何解决这个问题？
我正在尝试什么：
require 'rubygems'
require 'em/pure_ruby'
require 'appium_lib'
require 'eventmachine'
require 'selenium-webdriver'
caps = {}
caps["app"] = "C:/apk/Pb_debug_4.1.19-DEBUG1-20190416T143413Z-001/Pb_debug_4.1.19-DEBUG1/Pb_debug_4.1.19-DEBUG.apk"
caps["platformName"] = "Android"
caps["platformVersion"] = "7.0"
caps["deviceName"] = "EMULATOR29X0X6X0"
caps["autoAcceptAlerts"] = "True"
caps["newCommandTimeout"] = "3600"
caps["deviceReadyTimeout"] = "3600"
caps["automationName"] = "UiAutomator2"
caps["autoGrantPermissions"] = "True"
错误：
InvalidArgumentError: 'autoGrantPermissions' must be of type boolean: 'autoGrantPermissions' must be of type boolean (Selenium::WebDriver::Error::InvalidArgumentError)

我真的不知道该怎么做才能解决这个问题。感谢您的关注。
