Thanks Bojan for your quick reply.
Actually as per my requirement inside ‘group’ if getting a empty list ‘{}’, it should return false . But group.lengh is returning true even if list is empty(ie {}).
eg:
if JSON is like below it should return false.
“group”: [
{}
]

  @Gayathry, go with the following expression:
  
  $group.filter(x=>x.hasPath('ID')).length > 0

    @bojanvelevski: Thank you for sharing this.
    Can we check if the incoming JSON is empty or not using the same?
    
    Thanks.
