Groovy: Retrieve a value from a JSON based on an object - rest

Question

So I have a JSON that looks like this
{
"_embedded" : {
"userTaskDtoList" : [
{
"userTaskId" : 8,
"userTaskDefinitionId" : "JJG",
"userRoleId" : 8,
"workflowId" : 9,
"criticality" : "MEDIUM",
**"dueDate"** : "2021-09-29T09:04:37Z",
"dueDateFormatted" : "Tomorrow 09:04",
"acknowledge" : false,
"key" : 8,
},
{
"userTaskId" : 10,
"userTaskDefinitionId" : "JJP",
"userRoleId" : 8,
"workflowId" : 11,
"criticality" : "MEDIUM",
**"dueDate"** : "2021-09-29T09:06:44Z",
"dueDateFormatted" : "Tomorrow 09:06",
"acknowledge" : false,
"key" : 10,
},
{
"userTaskId" : 12,
"userTaskDefinitionId" : "JJD",
"userRoleId" : 8,
"workflowId" : 13,
"criticality" : "MEDIUM",
**"dueDate"** : "2021-09-29T09:59:07Z",
"dueDateFormatted" : "Tomorrow 09:59",
"acknowledge" : false,
"key" : 12,
}
]
}
}
It's a response from a REST request. What I need is to extract the data of key "dueDate" ONLY from a specific object and make some validations with it. I'm trying to use Groovy to resolve this.
The only thing I've managed to do is this:
import groovy.json.*
def response = context.expand( '${user tasks#Response}' )
def data = new JsonSlurper().parseText(response)
idValue = data._embedded.userTaskDtoList.dueDate
Which returns all 3 of the values from the "dueDate" key in the response.
I was thinking that maybe I can interact with a certain object based on another key, for instance let's say I retrieve only the value from the "dueDate" key, that is part of the object with "userTaskId" : 12.
How could I do this?
Any help would be greatly appreciated.

Answer 1

You can find the record of interest, then just grab the dueDate from that
data._embedded.userTaskDtoList.find { it.userTaskId == 12 }.dueDate
