  ### Bug Summary
  
  On the new AWX user interface, after creating a schedule with a valid rule, when clicking on the button "Finish" at step _4, we have an error 504 **Gateway Time-out** after 1 or 2 minutes. Indeed, when we repeat the process, we are disconnected from AWX.

  ### Steps to reproduce
  
  1 - After connection, we have an information panel "A tech preview of the new AWX user interface can be found here." Click on **here** to access to the new interface.
  
  2 - Click on "Schedules" on left panel.
  
  3 - On step 1, choose a name for schedule name, for instance "Test schedule" and a time zone, for instance **Europe/Paris**
  
  4 - On step 2, define a valid rule, for instance "DTSTART;TZID=Europe/Paris:20250213T081500
  RRULE:FREQ=DAILY;INTERVAL=1;WKST=SU;BYSETPOS=3;BYHOUR=16;BYMINUTE=0;BYSECOND=0"
  
  5 - No need to define any exception on step 3
  
  6 - On step 4, click on button "Finish" to launch the schedule
  
  ### Expected results
  
  The schedule runs and ends after a few seconds.
  
  ### Actual results
  
  After approximately 1 or 2 minutes, an error occurred "Gateway Time-out". 
  
  When we repeat the process, we noticed the same error and, after several times, we are disconnected from AWX.
  
  Sometimes, when we repeat the process, we noticed and othe error "This schedule will never run. If you have defined exceptions it is likely that the exceptions cancel out all the rules defined in the rules step."
