如何将对象项添加到计算的属性项以放置在路径参数中？

还有一个名为计算属性unresolvedIssuesGroupedByOffice，该属性返回如下数据：

{
   "Blue":[
      {
         "issue_id":"232121",
         "branch":"Blue"
      },
      {
         "issue_id":"231131",
         "branch":"Blue"
      }
   ],
   "Orange":[
      {
         "issue_id":"332111",
         "branch":"Orange"
      },
      {
         "issue_id":"333141",
         "branch":"Orange"
      }
   ],
   "Red ":[
      {
         "issue_id":"224444",
         "branch":"Red "
      },
      {
         "issue_id":"111111",
         "branch":"Red "
      }
   ]
}

      

        
Office
        
Number of Unresolved Issues
      
      

        
{{ branch }}
        
{{ issues.length }}
      
    

  {
    path: '/reports/unresolved-issues-by-office/:office_id',
    name: 'unresolved-issues-by-office',
    component: () =>
      import(/* webpackChunkName: "test" */ './components/UnresolvedIssuesByOfficeList.vue'),
    props: true
  }
