Sapper not exporting _error.svelte, it works on localhost but breaksdown in deployment

[krishgoel]

Hi , I am new to Svelte and facing an issue with a Sapper app deployed on Netlify (same issue with Vercel as well), both the hostings tend to not honor the already present _error.svelte file. I believe this should be a common problem but I couldn't find anything on the web. The link to the Github repo is https://github.com/KrishSkywalker/krishgoel.com-v2, the deployment can be found at https://v2.krishgoel.com/. Any help would be greatly appreciated and I'll be happy to give you a mention on the website itself. Thank you
