When adding episode: "audio_id required"
Describe the bug
I've been trying to add a new episode after unsuccessfully trying to update from 1.2.0 to 1.2.3 (all instructions followed: database change and php spark command), and am presented with an "audio_id is missing" error message! Can't add a new episode!
Steps to reproduce
usual steps to add an episode, mp3 seems to be uploading, but after that, the error message appears.
Expected behavior
upload completion and addition of episode
Actual behavior
error message
Relevant logs and/or screenshots
Paste any relevant logs - please use code blocks (```) to format console output, logs, and code as it's very hard to read otherwise.
Context
- Castopod: 1.2.0
- OS: Ubuntu server
- Browser: Brave and Firefox
- any other relevant context: I have added an episode #100 (closed) a few days ago, now am trying to add episode #94 (closed), not sure if that's relevant of can cause this error as well.
Possible fixes
EpisodeModel.php line 111: 'audio_id' => 'required', (but when I change that, there are other error messages)
