Preview incorrectly fails for media tweets

[Istora Mandiri]

What happened?

When testing out a media tweet, the preview generated on the pull request returned an error.

https://github.com/IstoraMandiri/twitter-together-testing/runs/8662022388

Media file /home/runner/work/twitter-together-testing/twitter-together-testing/media/cat.jpg does not exist

However the 'missing' image did exist and after merging, was tweeted as expected.

The preview should not have failed.
