When the the Request is Posted it is looking for properties on the FacetFilter
that are only relevant if it were to render an html result

Subject: Re: Problem with POST requests
Hi!
Could you please post the code of your component and the page? I'm having a
hard time understanding your scenario from your description.
Are you using a component or page as code that will upload something
to ElasticSearch when it is requested but not sending any response
back to the browser?
