Invalid preset "General/Fast 720p30" when using AUTOMATED_CONVERSION_PRESET

[ignazioc]

I'm using docker compose and I configured a watch folder for the automatic conversion.

I specified these env variables:

- AUTOMATED_CONVERSION=1
- AUTOMATED_CONVERSION_PRESET="General/Fast 720p30"
- AUTOMATED_CONVERSION_FORMAT=mp4
- AUTOMATED_CONVERSION_KEEP_SOURCE=1

But the conversion log shows one error "Invalid preset "General/Fast 720p30".
The preset is one of the built-in presets and I see and can use it from the GUI. The preset is also listed below the error:
