I keep getting a TypeError: What am I doing incorrectly?

using_a_function.py
"""
This is importing a function named `tweet` from a file
    that we unfortunately don't have access to change.

You use it like so:
>>> tweet("Hello this is my tweet")

If the function cannot connect to Twitter,
    the function will raise a `CommunicationError`
If the message is too long,
    the function will raise a `MessageTooLongError`
"""
from twitter import (
    tweet,
    MessageTooLongError,
    CommunicationError,
)


message = input("What would you like to tweet?  ")
CommunicationError = "An error occurred attempting to connect to Twitter. Please try again!"
MessageTooLongError = "Oh no! Your message was too long (...)"


try:
    tweet(message)
except CommunicationError:
    print("An error occurred attempting to connect to Twitter.  Please try again!")
except MessageTooLongError as e:
    print("Oh no! Your message was too long ({})".format(e))

Hi there, Eric Kramer ! You're defining CommunicationError and MessageTooLongError as strings. But those are defined elsewhere as types of Errors. But you've overwritten them now with strings.

Removing these two lines should cause the challenge to pass:

CommunicationError = "An error occurred attempting to connect to Twitter. Please try again!"
MessageTooLongError = "Oh no! Your message was too long (...)"

Hope this helps! :sparkles:
