Problem Reading From Thingspeak from Arduino - http

Question

I am using this code to retrieve data from a Thingspeak channel in a JSON format. I am using an ESP8266 along with an Arduino Nano 33 BLE. The Nono 33 BLE Arduino board is not compatible with Thingspeak library and it doesn’t support SoftwareSerial. Alternatively, I am using serial1 to communicate with the ESP8266 and REST API method to get the data from Thingspeak as it is shown in the code. However, I cannot get it to work. It is worth noting that Serial1.available() always gives zero even after adding delays.
I have used the same code to send data to the same Thingspeak channel and it works perfectly. I have no clue why it is not reading from the channel. I would really appreciate any help with this problem
Thanks in advance.
