How to use a variable mapping a json

Question

I need search the assets types in a json but mapping I have a block key that is different in all blocks. I set a variable that cointains this values but when I want to use do not retrive the things after this block key. This is the code

for (var i = 0; i < jsonResponse.items.length; i++) {
  var email = jsonResponse.items[i];
  var emailName = email.name;
  var block = jsonResponse.items[i].views.html.slots.banner.blocks;
  var blockKeys = [];
  var asset = jsonResponse.items[i].views.html.slots.banner.blocks.blockKeys.assetType;
  var assetName = asset.name
    
   for (var blockKey in block) {
       blockKeys.push(blockKey);
      } 
    Write("\n\Name: " + emailName);
    Write("\n\Blocks: " +(blockKeys));
    Write("\n\Asset Name: " + assetName);

And this is the response

Name: Test Email Dinamico
Blocks: hmjsixa2nda,74tda2do8en
Asset Name: undefined

Someone knows what is wrong?

Answer 1

The most likely explanation is that jsonResponse.items[i].views.html.slots.banner.blocks.blockKeys.assetType.name is undefined in the JSON response.

If you can provide a sample JSON response, we could confirm this.
