使用jq“contains”并在未找到键时抑制错误

我试图根据同一对象中另一个键的“contains”值获取值

我已经尝试过一个代码,它可以工作并输出我想要的结果,但是JSON中的一些对象没有这个键,如我所得到的:

jq: error (at <stdin>:1): null (null) and string ("BBC") cannot have their containment checked

或者这个错误的原因是其他键中的数组,我不确定

使用:

jq '.entries[] | select(.icon | contains("BBC")) | .uuid'

我希望找到的结果的UUID没有错误,并将其作为变量存储在shell中

"174501xxxxxxxxxxxxxe6342a03"

导入的输入文件

{  
   "entries":[  
      {  
         "uuid":"174501xxxxxxxxxxxxxe6342a03",
         "enabled":true,
         "autoname":true,
         "name":"BBC",
         "number":0,
         "icon":"file:///logos/BBC.png",
         "icon_public_url":"imagecache/1097",
         "epgauto":true,
