python random error IndexError: list index out of range

I try to import random user-agent from a randua.txt file using this

uat = open('randua.txt', 'r')
ua_rand = uat.read().splitlines()
rua = random.choices(ua_rand)
header = {'User-Agent': rua}
r = requests.get('https://www.google.com/', headers=header)
print('Status Code : '+r.status_code)

but i dont know whats wrong i already checked maybe some typo or any error but when i try the script in another file it work, only in this file and i get this error

Traceback (most recent call last):
  File "main.py", line 7, in <module>
    rua = random.choices(ua_rand)
  File "\Python\Python39\lib\random.py", line 487, in choices
    return [population[floor(random() * n)] for i in _repeat(None, k)]
  File "\Python\Python39\lib\random.py", line 487, in <listcomp>
    return [population[floor(random() * n)] for i in _repeat(None, k)]
