Help Creating Multiple Swim Sessions in Airtable Based on Date Range

What I'm Trying to Do

I'm building a Zap to create multiple swim lesson sessions in my Airtable base. I need to generate recurring swim sessions on specific days of the week (like Sundays) within a date range.

Here's my workflow:

1. Trigger: New record in my "session openings" table in Airtable
2. JavaScript step: Generate sessions for each Sunday between start date and end date
3. Loop step: Create individual records for each session in my "SUMMER SCHEDULE" table

Current Setup

1. Trigger: When a new record is created in my "session openings" table with:
   • Instructor (linked record)
   • Location (text)
   • Start Date (date/time)
   • End Date (date/time)
   • Repeating (single select - "Sunday")
2. Code by Zapier: JavaScript to generate all sessions between dates
   • This successfully generates 4 sessions (one for each Sunday)
   • Output includes: Session dates, day of week, instructor, location, etc.
3. Create Loop From Text: Trying to loop through my sessions
   • This is where I'm stuck - I can only get it to create one session

Problem I'm Having

My JavaScript generates multiple sessions correctly (I can see all 4 Sundays in the output), but I can't figure out how to properly set up the "Create Loop From Text" step to iterate through each session and create separate records in Airtable.

The JavaScript output looks like this:

Sessions Count: 4
Sessions Text: [JSON data for all 4 sessions]
firstSession: [Details of first session]

Questions

1. How do I correctly set up "Values to Loop" in the Create Loop From Text step to process all 4 sessions?
2. Should I modify my JavaScript to output data differently to work better with Zapier's looping functionality?
3. Is there a simpler approach to creating multiple recurring sessions based on a date range and day of week?

I appreciate any guidance on getting this automation working correctly. Thanks!
