In real I (try to) use ox-hug to export my org-files (org-roam-v2) to
markdown (and later to HTML).
After analyzing the my debug output [1] the ox-hugo people pointed me to
org-roam community because the error is "thrown" (correct term in
emas-lisp=?) by "org-export-resolve-fuzzy-link".
After revisiting this, I believe, this is something that needs to be fixed in ox-hugo as it is calling org-export-resolve-fuzzy-link directly without handling the broken link error.
I'll try to fix it in the next week.
