Performance metrics in 500 pages

Hi all!

I want to know if is possible to see all the waterfall in 500 error page like this https://pr.newhomesource.com/mvcerror

I ran several webpage test but it doesn’t show all the waterfall https://webpagetest.org/result/211102_AiDc64_65462793186dae1e69a6d4e6ea8e00d6/
