I have a single page application and therefore am using rendertron for dynamic rendering as recommended by google. Everything appears to be working well. All URL's are available to google from the live test in the search console. However when I test the page speed on PageSpeed Insights and I'm receving the following error: Lighthouse returned error: NO_FCP. Something went wrong with recording the trace over your page load. Please run Lighthouse again. (NO_FCP)

Url I'm testing is https://www.voro.com

Rendertron url https://rendertron-voro.herokuapp.com/render/https://www.voro.com

Is this expected behavior? Is there something wrong with my implementation?

    I had to look up what "NO_FCP" means. It stands for "No first contentful paint." First contentful paint is a web page performance metric that Google is pushing. When loading a page, it measures when the first text or image is rendered. Dec 16 '19 at 10:41
