MuleSoft JSON Array Filter - mule

Question

I am trying to extract formatted address, lat, lon using using google API. The JSON output looks like below:
var inpt = {
"results" : [
{
"address_components" : [
{
"long_name" : "94",
"short_name" : "94",
"types" : [ "street_number" ]
},
{
"long_name" : "Kinghorne Street",
"short_name" : "Kinghorne St",
"types" : [ "route" ]
},
{
"long_name" : "Goulburn",
"short_name" : "Goulburn",
"types" : [ "locality", "political" ]
},
{
"long_name" : "Goulburn Mulwaree Council",
"short_name" : "Goulburn Mulwaree",
"types" : [ "administrative_area_level_2", "political" ]
},
{
"long_name" : "New South Wales",
"short_name" : "NSW",
"types" : [ "administrative_area_level_1", "political" ]
},
{
"long_name" : "Australia",
"short_name" : "AU",
"types" : [ "country", "political" ]
},
{
"long_name" : "2580",
"short_name" : "2580",
"types" : [ "postal_code" ]
}
],
"formatted_address" : "94 Kinghorne St, Goulburn NSW 2580, Australia",
"geometry" : {
"location" : {
"lat" : -34.742658,
"lng" : 149.722802
},
"location_type" : "ROOFTOP",
"viewport" : {
"northeast" : {
"lat" : -34.7413090197085,
"lng" : 149.7241509802915
},
"southwest" : {
"lat" : -34.74400698029149,
"lng" : 149.7214530197085
}
}
},
"place_id" : "ChIJ_57nYeiuFmsR0ZLPJl7b2P0",
"plus_code" : {
"compound_code" : "7P4F+W4 Goulburn, New South Wales, Australia",
"global_code" : "4RQF7P4F+W4"
},
"types" : [ "establishment", "food", "point_of_interest", "store" ]
}
],
"status" : "OK"
}
Using Dataweave of MuleSoft 4, I wanted to filter payload by "types" which is an Array. My expected result should be:
location: "New South Wales"
To get the above result I tried expression like below:
%dw 2.0
output application/json
--
{
location: inpt.results.address_components filter ($.type contains "administrative_area_level_1")[0]."long_name"
}
But I am getting null result. Appreciate your help!

Answer 1

Super close, your results is an array. If you have more than one JSON object in the array, you'll need to map them. Here's a solution to the current question:
%dw 2.0
output application/json
---
location: (inpt.results[0].address_components filter ($.types contains "administrative_area_level_1"))[0].long_name

Answer 2

You can use this as well:
%dw 2.0
output application/json
---
{
(flatten (payload.results.address_components) filter ($.types contains "administrative_area_level_1") map {
location : $.long_name
})
}
