My HTML has links to google font apis:
<link href="https://fonts.googleapis.com/css?family=IBM+Plex+Sans:100,200,300,400,500,600,700&display=swap" rel="stylesheet">
<link href="https://fonts.googleapis.com/css?family=IBM+Plex+Mono:100,200,300,400,500,600,700&display=swap" rel="stylesheet">
Running inline() will throw an UnhandledPromiseRejection and kill the nodejs app. The error message is "Io Error: operation not supported on this platform". I replicated on MacOS and a RHEL container.
If I set load_remote_stylesheets: false then the problem stops.
Not sure if there is something specific about the google font api or a larger problem with loading remote stylesheets.
