// This code includes helper functions for compatibility with versions of the SDK prior to 1.0.9, which includes the dialog directives.

该代码最初可以正常工作，但是在我对Lambda代码进行了几次编辑后，我一次又一次收到相同的答复，这毫无意义。我认为问题可能出在以下事实：我为意外值添加了一个额外的值，并且在Skillinator.io网站上重建Lambda代码之前，我添加了一个自然值。由于我整天都在努力使用此代码，因此将不胜感激。
答案 0 :(得分：0)
“所请求的技能的响应有问题” 表示响应json出了点问题。它可能为null或无效。
在您的情况下，此行引发错误，因为您的字符串连接不正确。
speechOutput = "Ok. I will play " + noteSlot + accidental + <audio src="' + audioSrc + '" />;
将其更改为：
speechOutput = "Ok. I will play " + noteSlot + accidental + "<audio src=\"" + audioSrc + "\" />";
