Alexa.Presentation.HTML interface not supported on Echo Show devices?

I am working on a skill for the Echo Show and Fire Stick platforms that uses the Web Games API. That API is in public beta as of now. I can run my skill on my Fire Stick 4K device. But whenever I try to run my skill or the sample "playground" skill I get an error in my Lambda logs that states the Echo Show device does not support the Alexa.Presentation.HTML interface:


  "request": {
        "type": "SessionEndedRequest",
        "requestId": "amzn1.echo-api.request.bd6d1855-a1ec-434e-9c0b-8b5bf7cf7e89",
        "timestamp": "2020-02-04T14:26:10Z",
        "locale": "en-US",
        "reason": "ERROR",
        "error": {
            "type": "INVALID_RESPONSE",
            "message": "The device does not support Alexa.Presentation.HTML directives"
        }
    } 

This happens on both my original Echo Show and my new Echo Show 8. Both devices are fully updated.


I thought the Echo Show devices supported the Alexa.Presentation.HTML devices and therefore the Web Games API? How can I fix this?

Hi @Robert, were you able to find a solution here? I am facing the same issue and need help. I am getting the same error on echo show 5 and during certification they always tell me that HTML is supported on echo show. No Documentation or support of Amazon is able to help me here... Thanks in advance!
