[V3] migration of site build with V1.1 - errors encountered

[mi-hol]

As a follow-up to discussion about security issue in V1.1 I started migration to V3.

Got below error and am looking for some hints how to fix them

the related changes are in this branch

Update (after some change to migrated code):

pnpm build

> nextra-docs-template@0.0.1 build C:\Users\mholzer\Documents\git\boc-kb-v2
> next build

[mi-hol]

The root cause seems to be an error with content of next.config.mjs.
Still investigating...

[mi-hol]

After I removed next.config.mjs

Error messages explain finally what needs to be fixed :)

@dimaMachina since I recreated pages/_meta.js according to doc the strange errors started to re-appear.

VS Code complains about "Octal literals are not allowed. Use the syntax '0o1'.ts(1121)"
but the numeric prefix is just part of an existing directory name that worked in V1.1.

Any hint?

[mi-hol]

tried to run it locally via npnm dev on http://localhost:3000 gives Internal Server Error

while a vercel deployment to https://boc-kb-v2-aab9-1yglpjbso-mihols-projects.vercel.app
results in a distorted webpage

#3357 (comment)

[mi-hol]

the workaround did resolve the issue for now, but a permanent fix would be preferred
