First of all, I would like to create a page that takes the url paramter (e.g. /test/hell, which test is the page and hell is the parameter).
Therefore I created a page that takes the parameter and show it on the title (Example, with the added page link at the bottom), based on the Gatsby getting started project. It seems working.
But when I open the /test/hell page on the browser Webapge on the browser, it first pops up the 404 page and then flash back to the correct content (please refresh the page to see the 404 page). The 404 page is not what I expected so I am not sure if how to get this fixed. Also this problem is not being observed when I run Netlify/Gatsby locally.
This is the test page commit and this is the only commit that I made. I am not sure how to get ride of the 404 page being displayed.
