Quay.io API image build

Question

I am unable to build any image using quay REST API. The only error I can see is: Could not find or parse Dockerfile: First line in Dockerfile isn't FROM.

The dockerfile builds fine using other methods , the issue is only when using quay rest api.

This is the image build json:

{
  "docker_tags": [
    "v0.0.11"
  ],
  "archive_url": "http://host:port/app.zip"
}

The archive_url is accessible on local as well as on the network. The build works if the url points to a Dockerfile, but fails if it points to a zip. Are there any special requirements for this archive for quay server?
