error line 50, in thread = threading.Thread(target=run,args=(sys.argv[1],sys.argv[2],p)) IndexError: list index out of range

Here is my code:

import requests
import threading
import sys

max = threading.Semaphore(value=500) # Decrease this value if you encount problems with your cpu/ram usage.
threads = []
list = open('proxies.txt.txt', 'r')
proxies = list.readlines()
list.close()

def fetchData(channel='***a', post='2', proxy=None):
    try:
        r = requests.get('https://t.me/'+channel+'/'+post+'?embed=1', timeout=20, proxies={'https':proxy})
        cookie = r.headers['set-cookie'].split(';')[0]
        key = r.text.split('data-view="')[1].split('"')[0]
        if 'stel_ssid' in cookie: 
            return {'key':key,'cookie':cookie}
        else:
            return False
    except Exception as e:
        return False

def addViewToPost(channel='google', post='1', key=None, cookie=None, proxy=None):
    try:
        r = requests.get('https://t.me/'+channel+'/'+post+'?embed=1&view='+key, timeout=20, headers={
        'x-requested-with':'XMLHttpRequest',
        'user-agent':'Mozilla/5.0 (Windows NT 6.2; Win64; x64; rv:59.0) Gecko/20100101 Firefox/59.0',
        'referer':'https://t.me/'+channel+'/'+post+'?embed=1',
        'cookie':cookie}, proxies={'https':proxy}
        )
        return r.text
    except Exception as e:
        return False

def run(channel, post, proxy):
    max.acquire()
    s = fetchData(channel, post, 'https://'+proxy)
    if (type(s) is dict):
        l = addViewToPost(channel, post, s['key'], s['cookie'], 'https://'+proxy)
        if l != False: print('Proxy '+proxy+' finished its job successfully!')
    max.release()
    print('Thread with proxy '+proxy+' has been terminated.')

for proxy in proxies:
    p = proxy.split('\n')[0]
    thread = threading.Thread(target=run,args=(sys.argv[1],sys.argv[2],p))
    threads.append(thread)
    thread.start()
    print('Started new thread with proxy '+p)

It gives back this error :

Traceback (most recent call last):
