[SSG][Error handling] How to stack errors during SSG, and then invalid the build at exit?

[gustaveWPM]

Hello!
I have a question about something a little touchy with Next.js

Let's say I have errors that I can ONLY detect during the "Generating static pages" step.

How can I stack these errors, then fold them and throw them all at the END of the build?

Thanks in advance!
