Bookings Example with errors

I have opened the Wix Booking Example in Wix Editor and started in Preview the page Bookings/Services Services page. The page is not showing the Schedule data and not updating the duration.

Same effect is even in the published example.

In the developer console, the following error text is shown.

Loading the code for the Redirect page. To debug this code, open ghd6j.js in Developer Tools.

Loading the code for the Bookings/Services Services Service P... page. To debug this code, open xn88a.js in Developer Tools.

Failed to load initial data Error: Unknown error. Request ID: 1579462880.808149574450662316674. Message: UNKNOWN: Unknown token id -> List(15641d50-794e-4c80-ab88-1f7119d1918a).

TypeError: Cannot read property 'serviceDurationInMinutes' of null

I have tried the example on the following link https://www.wix.com/corvid/example/service-page.

Can someone comment or give advise how to correct this code? thanks.

PS I created the example from scratch in another web site and the following error text shows.

Loading the code for the site. To debug this code, open masterPage.js in Developer Tools.

Loading the code for the Bookings/Services (Slug) page. To debug this code, open quxdr.js in Developer Tools.

Something with Operator LT and GT.

Thank you for bringing this to our attention. We have forwarded this information to the relevant department and will contact you as soon as there is any feedback.

+1 - Do we have a response? The given example doesnt seem to work…

I found one way of working around this problem. Simply create a new page and ensure it is able to query and resolve the URL slug in the preview mode. If it can, then go ahead and copy all the code across and it should work.
