PPTX to HTML5 Conversion Issue - Parameter Is Not Valid

I’m currently testing aspose.slides capabilities using the supplied cloud docker image.

When I try to convert a pptx to html, everything seems to work fine.
When I used the exact same curl to convert to html5 instead, I get the following error:

{
  "requestId": "3a41cad4-0b29-4c2a-9344-0a10b5c58cce",
  "error": {
    "code": "internalError",
    "message": "Parameter is not valid.",
    "description": "Operation Failed. Internal error.",
    "dateTime": "2022-05-17T15:58:51.9296345Z"
  }
}

I’ve tried pointing the curl to the non-self-hosted cloud API and I get the same error.
This is the curl cmd I’m using;

curl -X POST 
	"http://localhost:3030/v3.0/slides/convert/html5" 
	-F "file=@test.pptx"  
	-H "accept: multipart/form-data" 
	-o "testoutput.html"
