What is parallel error?

Sometimes, a meeting may get canceled automatically. This usually happens because of a parallel error.

A parallel error occurs when two people try to book and pay for the same time slot at the exact same moment. Since only one person can successfully book that slot, the system confirms the meeting for one user and cancels it for the other.

Example Use case

Let’s say Alex and John both try to book a meeting with a mentor at 3:00 PM.

  • Alex clicks “Pay” at 3:01:05 PM.

  • John clicks “Pay” at 3:01:07 PM (just 2 seconds later).

Since both tried to pay for the same slot, the system books the meeting for Alex (who paid first). John's booking attempt gets canceled, and her payment is refunded immediately.

This ensures there are no double bookings for the same time.
