Bug Report: Unexpected end of JSON input when scheduling actor

Hi, I am a public developer and my users are experiencing an issue when they schedule my actor. This is reproducible:

1. Create schedule for actor
2. Click Edit
3. Regular and JSON input is missing and error Unexpected end of JSON input (see screenshot)
4. This results in actor not getting any input during the scheduled run and failing

This appears to be a bug in the apify platform. I am using INPUT_SCHEMA.json in yhe root directory of mt actor. Let me know if theres anything I need to change on my side to get this working!
