I want to get the value of the variable in the JSON but it keeps on giving me undefined index where the index is definitely there when I open the URL.

Here is my code:

 //initializing cURL
            $ch = curl_init();
//setting the URL
            $priceURL = '';
//set options
            curl_setopt($ch, CURLOPT_URL, $priceURL);
            curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
            curl_setopt($ch, CURLOPT_HEADER, 0);
            $string1 = curl_exec($ch);
//close curl session/free resources
            curl_close ($ch);
//decode the json string into an array
            $json_price_file = json_decode($string1, true);
            $price = $json_price_file ["lowest_price"];

It gives an error of Undefined index: lowest_price. However, when you open the URL, the variable is definitely there. What am I missing? Please help :D
