Python: TypeError: object of type 'NoneType' has no len(): Using JSON And rncryptor

Question

from selenium import webdriver

import json
import rncryptor
import string
import random

letters = string.ascii_letters
current_folder = os.path.realpath(os.path.abspath(os.path.split(inspect.getfile(inspect.currentframe() ))[0]))
cryptor = rncryptor.RNCryptor()

def init_driver():

    driver = webdriver.Chrome(executable_path = chromedriver)
    return driver

        with open(os.path.join(current_folder,"config.json"), 'w') as f:
            f.write(json.dumps(d))

def firstruntrue():
    user = input("What is your Username? ")
    password = input("What is your Password? ")
    key = ''.join(random.choice(letters) for i in range(20))
    editjson("key", key)
    encrypted_user = cryptor.encrypt(user, key)
    editjson("user", encrypted_user.decode('utf-8', 'ignore'))
    encrypted_pass = cryptor.encrypt(password, key)
    editjson("password", encrypted_pass.decode('utf-8', 'ignore'))
    editjson("firstrun", "False")

with open(os.path.join(current_folder,"config.json"), "r") as handler:
    info = json.load(handler)
    user = info["user"]
    password = info["password"]
    firstrun = info["firstrun"]

#First Run
if "True" in firstrun:
    firstruntrue()
#Reload after edit with firstrun()
with open(os.path.join(current_folder,"config.json"), "r") as handler:
    info = json.load(handler)
    user = info["user"]
    password = info["password"]
    firstrun = info["firstrun"]
    key = info["key"]

#Chrome Script
if __name__ == "__main__":
    user1 = cryptor.decrypt(user, key)
    password1 = cryptor.decrypt(password, key)
    driver = webdriver.Chrome()
    driver.get(REDACTED)
    User_box = driver.find_element_by_id(REDACTED)
    User_box.send_keys(user1)
    Password_box = driver.find_element_by_id(REDACTED)
    Password_box.send_keys(password1)
    search_box = driver.find_element_by_id(REDACTED)
    search_box.submit()
    sys.exit()

C:\Users\REDACTED\Desktop\REDACTED>python REDACTED.py
What is your Username? REDACTED
What is your Password? REDACTED
Traceback (most recent call last):
  File "REDACTED.py", line 57, in <module>
    user1 = cryptor.decrypt(user, key)
  File "C:\Users\REDACTED\AppData\Roaming\Python\Python37\site-packages\rncryptor.py", line 104, in decrypt
    n = len(data)
TypeError: object of type 'NoneType' has no len()

I get this error when I run this code. What am I doing wrong? Python 3.7
