Python Random User Agent Library Error

I've been using random user agent library to assign a random user-agent to each request,

from random_user_agent.user_agent import UserAgent
from random_user_agent.params import SoftwareName, OperatingSystem


# you can also import SoftwareEngine, HardwareType, SoftwareType, Popularity from random_user_agent.params
# you can also set number of user agents required by providing `limit` as parameter

software_names = [SoftwareName.CHROME.value]
operating_systems = [OperatingSystem.WINDOWS.value, OperatingSystem.LINUX.value]   

user_agent_rotator = UserAgent(software_names=software_names, operating_systems=operating_systems, limit=100)

# Get list of user agents.
user_agents = user_agent_rotator.get_user_agents()

# Get Random User Agent String.
user_agent = user_agent_rotator.get_random_user_agent()


result = requests.get(url, headers={'User-Agent':f'{user_agent}'})

At some point when sending requests, my user agent would look like this:

\tMozilla/5.0 (Windows NT 6.3; WOW64)  AppleWebKit/537.36 (KHTML, like Gecko) Chrome/42.0.2311.90 Safari/537.36

the \t would cause my request to fail with the above error message, is this a library bug?

one way would be to use strip() on user_agent

but the more efficient way I believe would be to specify at the below step choose only from those starting with 'Mozilla' and then strip()? As the library may contain wrong user agents, how could I implement that?

user_agent = user_agent_rotator.get_random_user_agent()

So here specify user_agent_rotator.get_random_user_agent() only starting with 'Mozilla' then strip()?
