No assets after deployment to Vercel

[sergeyClover]

Hello. I have been testing out the application and it seems like asset files such as HTML templates for emails and invoices are not present in .next folder after build.

I tried a few things in next.config.js as well as some testing with changing "copy-standalone" script but nothing seems to work.

Error:Unhandled Promise Rejection {"errorType":"Runtime.UnhandledPromiseRejection","errorMessage":"Error: ENOENT: no such file or directory, open '/var/task/.next/server/chunks/assets/invoice/template.html'","reason":{"errorType":"Error","errorMessage":"ENOENT: no such file or directory, open '/var/task/.next/server/chunks/assets/invoice/template.html'","code":"ENOENT","errno":-2,"syscall":"open","path":"/var/task/.next/server/chunks/assets/invoice/template.html","stack":["Error: ENOENT: no such file or directory, open '/var/task/.next/server/chunks/assets/invoice/template.html'"," at Object.openSync (node:fs:596:3)"," at Object.readFileSync (node:fs:464:35)"," at getStaticAssetFile (/var/task/.next/server/chunks/4161.js:96:52)"," at /var/task/.next/server/chunks/7256.js:506:359"]},"promise":{},"stack":["Runtime.UnhandledPromiseRejection: Error: ENOENT: no such file or directory, open '/var/task/.next/server/chunks/assets/invoice/template.html'"," at process.

Help would be appreciated. :)

Hi, and thanks for your request!

Your issue is most likely related to this issue of the next.js framework, which is the base of this project:
vercel/next.js#32236

I have followed this issue a long time already and it seems that there's still no viable solution for this, but if you have an idea, please let me know! I "fixed" the issue by moving away from vercel and hosting the project on heroku. Unfortunately, they abounded their free tier.

Just found out a solution:

1. Move assets folder to project root
2. Now assets are accessible with command:
   let basePath = process.cwd();
   const filePath = path.join(basePath, assets/${file});

hope it helps someone in the future ;)

I'm glad to hear that you found a solution! Do you know if the code works in all three environments: development, production, and standalone production?

Works in vercel production environment. Didnt test on dev or standalone just yet as it seems that puppeteer is not working as well on vercel.
