How to write condition in task to check null value while running workflow

[heramb_sawant]

In my workflow 

Task_1 is  DQL type task  which might have null values in output , like given below 

[
{
"name" : "ABC",
"age": 10,
"height": 6
}
]

or

[
{
"name" : "ABC",
"age": 10,
"height": null
}
]


I would like to run next task only if height value is no null

How Can I write condition ??

Thanks in advance

Hello,

On the next task, under conditions, try something like this:

{{ result("Task_1").records[0].height != None}}

Change "Task_1" if that's not the correct name of the DQL task.
