YouTrack工作流程重置字段值

Question

我有一个YouTrack的JavaScript工作流，当问题设置为Open时，应该将几个字段重置为＆＃34; null＆＃34;。这是我用来完成此任务的代码：

Open: {
  onEnter: function (ctx, issue) {
    issue.fields['Alpha Approved By'] = null; // <- This is where the error points
    issue.fields['UAT Approved By'] = null;
    issue.fields['QA Approved By'] = null;
    issue.fields['PM Approved By'] = null;
  },
  transitions: {
    Working: {
      targetState: 'In Progress'
    },
    Rejected: {
      targetState: 'Rejected'
    }
  }
},

但是，每当我尝试创建问题时，都会收到以下错误消息： TypeError: Cannot read property "fields" from undefined (workflow-enforcement/workflow-enforcement#20)

第20行在代码段中标有<注释

我应该如何设置这些字段的值？

Answer 1

issue是上下文对象（ctx）的一部分，而不是参数。因此代码应如下所示：

onEnter: function (ctx) { var issue = ctx.issue; issue.fields['Alpha Approved By'] = null; ... }
