I found the problem in the @nylas/web-elements package, version 2.2.1 - in the NylasScheduling component during the reschedule flow. When booking an event, we get a booking_ref that we can use to reschedule the event. Using the NylasScheduling component in version 2.2.1 - the logic for decoding booking_ref to booking_id, configuration_id is broken under the hood - the values are unrealistic and corrupted, which results in the component crashing with an error that “configuration doesn’t exist”. Steps to reproduce: Book an event based on a public configuration Take the bookingRef and insert it into the nylas-scheduling component - the @nylas/web-elements version must be 2.2.1, because in 2.1.0 everything works as expected. In the request - https://api.us.nylas.com/v3/scheduling/ui-settings you’ll see an error saying “configuration not found”. Compare your configuration ID with the configuration_id that was sent in the request above. Please show this to your developers. The problem exists. And yes, just to clarify - I tested with the same exact logic between versions 2.2.1 and 2.1.0 [image] [image]

Hi @Oleksandr , you’re right - that is a bug, and we’re working on fixing it now. I’ll update you as soon as a fix has been released. Thank you for bringing it up!

@nick.barraclough Could you please pay attention to another one of my topics, there’s also a problem there. Link below: [image] Missing 'participants' parameter support in Scheduler UI packages: @nylas/react and @nylas/web-elements Question and Answers Let me explain once again what I need. We have a configuration for Nylas Scheduling. Each configuration has a participants object that includes booking and availability objects… availability - for checking availability across calendars (this works as needed) booking - here you can specify which calendar to book the event to (for each participant), but there’s an interesting point, here’s your description for this field: “The booking data for the participant. If omitted, the participant is not…

Any update on this? It seems like there have been minor updates to the web-elements package (2.2.4 was released 8 days ago), but I’m still having this issue. Also is there a github repository for the https://www.npmjs.com/package/@nylas/web-elements package?

Hi, Are you getting the same booking not found error with the latest version? Are you using our react components or the web elements directly, and do you have a minimal reproducible code by any chance? Thank you
