[Bug]: Scheduled Transaction won't save if dollar sign in Schedule Name

### What happened?

I was trying to create a scheduled transaction today with a dollar sign in the name, and the red "Something went wrong" error message came up. I've cleared cache and repaired database with same result. Posting same scheduled transaction without dollar sign works.

This occurs if schedule is repeating or not.

### How can we reproduce the issue?

1. Go to Schedule
2. Put dollar sign in Schedule Name (additional characters irrelevant)
3. Enter transaction settings
4. Click Save
