load assetbundles dynamically from JSON - Unity Vuforia

Question

I have created an app where I am trying to load the asset bundles from a JSON file.

JSONNode targetAsset = JSON.Parse(request.downloadHandler.text);

int counter = 0;
for (int i = 0 ; i < targetAsset.Count ; i++) {
    counter++;
    if (targetAsset[i]["targetid"].Value.Equals(targetAsset[i][0])) {
        Debug.Log("It exists!");
        break;
    }
}

Using break loads index 0 assets from the JSON on every image target and without break, it loads the last asset from the JSON. But I want to load a particular asset on a particular image target. I tried the below code but it didn't work.

if (targetAsset[i]["targetid"].Value.Equals(targetAsset[i][0])) {
    Debug.Log("It exists!");
    if targetAsset[i][0] == uniqueTargetID; # uniqueTargetID is a variable called from SimpleCloudRecoEventHandler class.
        break;
}

Here is my JSON file:

[
    {
        "targetid": "sometargetalphanumericfromvuforia",
        "assetbundle":"urlofassetbundle",
        "prefab": "Assets/Prefabs/xyz1.prefab",
        "AssetName":"xyz1"
    },
        {
        "targetid": "sometargetalphanumericfromvuforia",
        "assetbundle":"urlofassetbundle",
        "prefab": "Assets/Prefabs/xyz2.prefab",
        "AssetName":"xyz2"
    }
]

I am using Vuforia's latest version, with Unity 2019 and creating an app for android platform.
