Encountering a reference error during the gatsby build process

My project was functioning well as usual until I attempted to run 'gatsby build' and encountered the following error message:

ReferenceError: Cannot access '_404' before initialization

as well as

ReferenceError: Cannot access '_mdx_slug_' before initialization

I haven't made any recent changes that could have caused this issue, and I am unsure of the source of the problem. It seems to be related to the way gatsby is constructing the website's pages, but my level of expertise is not advanced enough to pinpoint the exact cause.

gatsby build output:

success load gatsby config - 0.041s
success load plugins - 0.757s
success onPreInit - 0.029s
success initialize cache - 0.046s
success copy gatsby files - 0.183s
...

Any assistance or insight on this matter would be greatly appreciated. Thank you.

Answer №1

After much exploration, I managed to discover a solution on my own. The issue stemmed from a specific call to document.documentElement that was disrupting the creation of static HTML files during the build process. It remains a mystery why this call was pointing to two different pages, even though it was located on a separate page. Fortunately, everything is now functioning as intended. For those facing similar challenges, consider encapsulating your window or document calls within a useEffect() hook or an if statement such as 

if(typeof window !== 'undefined')
. May this advice prove beneficial to others in similar situations! Best of luck.
