MediaService reads PublicScheduleWebinarRequest with a bare ObjectMapper, where FAIL_ON_UNKNOWN_PROPERTIES is true. The demo page also sends ***Payload, so every schedule, join and demo-request call failed deserialization and Spring answered a bare 400 "Bad Request" before any controller ran. Ignore unknown properties on the DTO.
