尝试为Zapier创建正则表达式时出错

Question

已解决：错误原因是我声明输出var的方式，请参阅代码

我正在尝试创建一个正则表达式来从VSTS附件获取URL以便与Jira同步。我尝试使用以下输入创建Run Javascript块：

我想要检索的是＆＃34;位置＆＃34;，所以我认为这会产生诀窍：

var regEx = new RegExp('location: (.*)', 'g'); // As mentioned in the comments, the 'g' part is not needed
var path = regEx.exec(inputData);
// output = path[1]; This was failing miserably
var output = [{'path': path[1], 'hello': 'world'}] //This works just fine, I guess the hello world part is not really needed :)

但我总是收到错误：

TypeError: Cannot read property '0' of null

我已经尝试创建一个简单的javascript测试来运行相同的，它工作得很好。你能帮我吗？
