Exporting media_player entity for Denon to Alexa

I am using the Denon integration and my amp refuses to add to Alexa as a smart home device. I used the smart home schema validator and the schema for my devices validates. I can’t figure out why Alexa won’t recognize my amp, while it does recognize my projector. Any ideas on how to debug this? How can I get errors from Amazon as to why it does not like my new device?
