When following documentation guide: TweepError: Failed to send request: Only unicode objects are escapable. Got <generator object to_unicode.<locals>.<genexpr> at 0x000001E0C87505F0> of type <class 'generator'>.

[Nowado]

I'm trying to follow basic guide from documentation at https://tweepy.readthedocs.io/en/latest/getting_started.html
Code fails at second step. I'm running code in jupyter, in case that's relevant.

auth = tweepy.OAuthHandler(API_KEY, API_SECRET)
auth.set_access_token(ACCESS_TOKEN, ACCESS_TOKEN_SECRET)

api = tweepy.API(auth)

I provide API key, API secret key, Access token, Access token secret as consumer_key, consumer_secret, access_token, access_token_secret respectively. This (seemingly) works.

user = api.get_user('twitter') fails returning error from the title.

Full log above.

I tried googling around and found multiple answers, including older issues in this repo, but none of them work or address the issue (somehow). I'd like to imagine following first steps of example from documentation I shouldn't be able to screw up too much.

What can be wrong, how to fix it?

You're passing a generator as one or more of the credentials. They need to be strings or bytes.

For code block usage, see https://docs.github.com/en/free-pro-team@latest/github/writing-on-github/creating-and-highlighting-code-blocks.

I am receiving this error when using a Docker container, @Nowado did you determine how you were passing a generator type as parameter? I've confirmed mine should all be interpreted as strings by printing their type. The code below runs fine locally but throes the error in this post's title when executed in a container:

auth = tweepy.OAuth1UserHandler(API_KEY, API_KEY_SECRET, ACCESS_TOKEN, ACCESS_TOKEN_SECRET)

I don't remember, sorry : (
