Error message: is not a Valid URL

Hey there,

Trying to render a JSON report generated using Lighthouse 5 in the viewer hosted on Github.
I made a public Gist with the content of the Lighthouse response object, but an error pops up: `Is not a valid URL`.

Here is the link: https://houssein.me/lighthouse/viewer-wordpress/?gist=ee3e6c422749f7a0fc6dcf68097cef8b

Do you have an idea where this issue originates from?

On another subject, I am using this [React package](https://github.com/blencorp/react-lighthouse-viewer) to render Lighthouse reports. How can I render a report with the Wordpress recommendations?

Cheers, and thanks for your work
