Cannot get array property by using Parse JSON groovy - json

Question

I'm new to Groovy. But, I can try with some simple code lines to extract the data.
I have read the from Parse JSON using groovy script (using JsonSlurper). But it didn't help in my case.
My code line:
{
"errors": false,
"address_data": [
{
"address_id": "567",
"township": {
"id": "41079",
"name": "Test Data"
},
"city": {
"id": "1622",
"name": "Test City"
},
"region": {
"id": "663",
"name": "Metro Test"
},
"stock_source_code": "Test",
"is_default_address": false
},
{
"address_id": "45444",
"township": {
"id": "41079",
"name": "Test Test"
},
"city": {
"id": "1622",
"name": "Test City"
},
"region": {
"id": "663",
"name": "Metro Test Taguig"
},
"is_default_address": true
},
{
"address_id": "45444",
"township": {
"id": "888888",
"name": "Apas"
},
"city": {
"id": "432",
"name": "Test City"
},
"region": {
"id": "591",
"name": "Test Cebu"
},
"stock_source_code": "testce",
"is_default_address": false
}
]
}
My code lines:
def response = "data_above";
def object = new JsonSlurper().parseText(response);
def errors = object.errors
if (errors == false) { //could access object.errors property
log.info "Checking condition"
def addressData = object.address_data // Cannot get the data
}
How can I get the address_data property?
