3817579 - Error in logs: "Date of birth missing; 7-1710; DateOfBirth" when booking Travelfusion supplier

When Date of Birth is a mandatory field for Travelfusion bookings, the DOB should be pulled from the user’s profile if filled in, be automatically shown in the TF pop-up window and sent to Travelfusion. However, this has intermittently not been happening and the bookings fail with error “Date of birth missing; 7-1710;” even though users have their DOB saved in their profiles.

In Kibana log, we can find this error:
Date of birth missing; 7-1710; DateOfBirth; 11/01/2023-15:55 (date and time of booking)
