Posting to Mastodon fails with Twitter video

[DylanVanAssche]

Description

I retweeted this Tweet: https://twitter.com/codingfield/status/1271165048350806016 which contains a Twitter video.
But the tool cannot post it to Mastodon for some reason, the server replies with HTTP 500.
On the next run, the tool tries and fails again, as a result, none of the Toots or Tweets are synced anymore.

Or can it be that my Mastodon server is improperly configured? I have a NGINX reverse proxy in front of it.

Steps to reproduce

1. Retweet a Tweet with a video, that seems to trigger it
2. Sync
3. HTTP 500 is returned from Mastodon's server

Environment

• rustc 1.41.0
• Ubuntu 18.04 LTS
• master branch

This appears in the logs of my Mastodon server:

But nothing more unfortunately...
