It's all in the title, I found a bug in the AI Translations plugin.
The problem is fairly easy to reproduce.
Just try to translate a record that contains an image field with the following attributes:
- Enable localization on this field -> checked
- Require alt and/or title -> checked + Alternate text
The translation will fail every time.
For the record, I used OpenAI (ChatGPT) as AI vendor.
Please don't hesitate to reach me if you require any further information.
