urequests: 'Response' object has no attribute 'headers'

For ESP32 with esp32-[ota-]20220618-v1.19.1.bin on LILYGO/TTGO T-Display

MicroPython v1.19.1 on 2022-06-18; 4MB/OTA module with ESP32
MicroPython v1.19.1 on 2022-06-18; ESP32 module with ESP32

headers are not available:

>>> r = urequests.get("https://micropython.org/")
>>> r.status_code
200
>>> r.headers
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'Response' object has no attribute 'headers'

The nightly build does not manage to connect to WiFi.
Similar code had no issue with the RP2040 (Pi Pico) port.

I've tried to provide a callback for parse_headers to see what's going on but get TypeError: unexpected keyword argument 'parse_headers'.

Here are the headers that should be available:

$ curl -s -D - -o /dev/null "https://micropython.org/"
HTTP/2 200 
server: nginx/1.10.3
date: Sun, 19 Feb 2023 09:11:34 GMT

It's because these features were added just after the v1.19.1 release:

• micropython/micropython-lib@5854ae1
• https://github.com/micropython/micropython-lib/commits/master/python-ecosys/urequests

Is is necessary to get a post v1.19.1 release to access the improved urequests or can I update just that library?

I assume installing the library using wip would get the latest version and use it instead of any baked-in libraries (I don't know for sure). You could probably also manually install the file or paste the code in your project.
