UI Builder - Calendar component invalidates the page being createdDescriptionWhen creating a new page with UI Builder and adding the Calendar component into it, the page in progress can only be saved once. After saving the page the first time, the save button is greyed out and deactivated, modifying or adding components to the page does not reactivate it.Further, when reloading the whole browser page and/or opening another UI Builder, switching to any other page and then going back to the one with the Calendar, the page tries to load but never finishes.Steps to Reproduce 1. In UI Builder click on display name (base agent workspace).2. Create a new page.3. Add a Calendar component to the page.4. Save your progress. Notice the Save button gets then greyed out.5. Add any other component to the page and/or do any modification to the current component. Notice the Save button is still not active so the changes can not be saved.6. Reload the page or open some other page in the UI Builder.7. Try opening the first test page with the Calendar component again. The page and the component will not load.WorkaroundThis can be caused by the component containing emojis in the timeline sections property. In this case you can find the error error below in the system log: Cannot generate object: com.glide.rest.util.RESTRuntimeException: Cannot generate object: com.glide.rest.serializer.impl.JSONSerializer.handleSerializeException(JSONSerializer.java:166). After removing those emoji's from the timeline sections content, the page will handle the now-calendar component without any issues.
