I'm not exactly sure why but domTransformation function is called 2 times for a single percySnapshot call. First time it's called with an empty <html><body> document so hoistAppDom fails with message like:

ERROR: Could not transform the dom: TypeError: Cannot read property 'innerHTML' of null

This is actually visible in the test log of this very project, for example this build (expand "Percy Test"): https://github.com/percy/ember-percy/runs/1055338113

Maybe there's a better fix for this but I'd really like to get rid of those annoying error logs 😅

Whoops, looks like GH actions does not allow me to run a build with a real PERCY_TOKEN, but I just tried this in our app and the log message is gone, and percy build looks fine as well.
