输出到控制台的所有消息都有前缀 [Ad Placement API]:
您只能设置 preloadAdBreaks 一次:
- 已调用 
adConfig()以设置值为<VALUE>的preloadAdBreaks 
已尝试调用 adBreak(),但系统仍在处理针对 adBreak() 的另一项调用(确保您没有通过其他工作器触发广告,并且没有在回调函数中调用 adBreak()):
Cannot show ad while another ad is already visible.
执行您提供的任意回调时失败:
<CALLBACK NAME> callback threw an error: <ERROR>
代码参数存在错误:
Invalid data-ad-frequency-hint value: '<VALUE>'. It must be in format 'Xs' where X is a number.Unsupported data-adbreak-test value '<VALUE>'. Supported values: 'on'.
adConfig() 参数验证错误:
Invalid ad config: <ERROR>.。其中<ERROR>可以是:preloadAdBreaks must be one of ['auto', 'on']sound must be one of ['on', 'off']onReady必须是函数
adBreak() 参数验证错误:
Invalid placement config: <ERROR>。其中<ERROR>可以是:missing required properties <LIST OF PROPERTIES><CALLBACK NAME> must be a function<PROPERTY NAME> must be one of <LIST OF VALID VALUES>the following properties are not used for the given ad type: <LIST OF PROPERTIES>
adBreak() 中重命名的回调(beforeBreak、afterBreak 和 adComplete)已分别重命名为 beforeAd、afterAd 和 adViewed。重命名后的运作方式没有变化):
Placement config: <OLD> has been renamed to <NEW>. Please update your code.Invalid placement config: <OLD> has been renamed to <NEW>. Cannot pass both fields. Please use <NEW> only.
