instapy-cli: [BUG] OSError: Unable to Upload

I cannot upload to Instagram with InstaPy-CLI using unchanged python scripts which used to work just 2 days ago.

I have two files (master.py and exec.py). I run exec.py to carry out the functions in master.py.

Master.py:

import urllib.request
from PIL import Image, ImageOps
from instapy_cli import client
from datetime import date

def get_item_shop():
    url = "http://api2.nitestats.com/v1/shop/image?footer=USE%20CODE:%20%22DISTURBED%22"
    urllib.request.urlretrieve(url, "itemshop.jpg")

def resize():
    desired_size = 1728
    im_pth = "itemshop.jpg"

    im = Image.open(im_pth)
    old_size = im.size  # old_size[0] is in (width, height) format

    ratio = float(desired_size)/max(old_size)
    new_size = tuple([int(x*ratio) for x in old_size])
    # use thumbnail() or resize() method to resize the input image

    # thumbnail is a in-place operation

    # im.thumbnail(new_size, Image.ANTIALIAS)

    im = im.resize(new_size, Image.ANTIALIAS)
    # create a new image and paste the resized on it

    new_im = Image.new("RGB", (desired_size, desired_size), (30,30,30))
    new_im.paste(im, ((desired_size-new_size[0])//2,
                        (desired_size-new_size[1])//2))

    output_path = 'itemshop2.jpg'
    new_im.save(output_path)





def post():
    today = date.today()
    d2 = today.strftime("%B %d, %Y")

    heart = "\U00002764"

    username = 'fbr.itemshop'
    password = 'Albion0411'
    cookie_file = 'cookie.json'

    image = 'itemshop2.jpg'
    text = 'Daily item shop for ' + d2 +'.' + '\r\n' + '\r\n' + 'Rate this item shop from 1-10!' + '\r\n' + '\r\n' + 'Use code: "Disturbed" to support me! ' + heart + '\r\n' + '#fortnite #itemshop #dailyitemshop #fortniteitemshop'


    with client(username, password, cookie_file=cookie_file, write_cookie_file=True) as cli:

        cookies = cli.get_cookie()

        cli.upload(image, text)

Exec.py:

import master
import time

master.get_item_shop()
print("Item shop saved.")
time.sleep(5)
master.resize()
print("Image resized.")
time.sleep(5)
master.post()
print("Image posted.")

These scripts fetch the Fortnite Item Shop image from nitestats.com API, resizes it to 1:1 for IG, and uploads it. Saving the image and resizing still works, but posting to IG doesn’t. As the item shop refreshes every day at 00:00 for me, I use crontab on my RPi to schedule the running of these python scripts. It has worked in the past, so I know crontab has no errors. However, I set crontab to write to a log so that I could see if anything went wrong. Below is what I got.

Logs

This is what is outputted to a log when the scripts are functioning:

Item shop saved.
Image resized.
[IG] not found cookie/cookie_file >> login as default
SAVED: COOKIE_FOR_USER.json
Done.
Image posted.

And, when they’re not working:

Item shop saved.
Image resized.
[IG] re-use cookie from COOKIE_FOR_USER.json
Error is >>
    Bad Request

Something went bad.

I have searched Google for this issue, and the only thing I could find was saying that Instagram have declined my request to upload. I have attempted to run the code on Windows, which gave the same issue, with and without a VPN, with different Instagram accounts, reset the passwords, and tried to use the scripts with and without the cookie file. I am fairly new to Python and would appreciate any help possible.
