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". "org-export-with-broken-links" is set to "t" (checked via "C-h v"). It is my will that this link is dead. That is not an error for me in my environment/workflow they are reminders for me. This is the full debug output (incl. line numbers): 1 Debugger entered--Lisp error: (org-link-broken "roam:git") 2 signal(org-link-broken ("roam:git")) 3 org-export-resolve-fuzzy-link((link (:type "fuzzy" :path "roam:git" :format bracket :raw-link "roam:git" :appli$ 4 #f(compiled-function (link) #<bytecode 0x158ff9168c05>)((link (:type "fuzzy" :path "roam:git" :format bracket :$ 5 #f(compiled-function (--data) #<bytecode 0x158ff9168c65>)((link (:type "fuzzy" :path "roam:git" :format bracket$ 6 mapc(#f(compiled-function (--data) #<bytecode 0x158ff9168c65>) (#("SSH-Key for Codeberg.org erstellen, um ohne $ 7 #f(compiled-function (--data) #<bytecode 0x158ff9168c65>)((paragraph (:begin 155 :end 294 :contents-begin 155 :$ 8 mapc(#f(compiled-function (--data) #<bytecode 0x158ff9168c65>) ((paragraph (:begin 155 :end 294 :contents-begin$ 9 #f(compiled-function (--data) #<bytecode 0x158ff9168c65>)((section (:begin 155 :end 295 :contents-begin 155 :co$ 10 mapc(#f(compiled-function (--data) #<bytecode 0x158ff9168c65>) ((section (:begin 155 :end 295 :contents-begin 1$ 11 #f(compiled-function (--data) #<bytecode 0x158ff9168c65>)((headline (:raw-value "Ziel" :begin 148 :end 295 :pre$ 12 mapc(#f(compiled-function (--data) #<bytecode 0x158ff9168c65>) ((section (:begin 1 :end 148 :contents-begin 1 :$ 13 #f(compiled-function (--data) #<bytecode 0x158ff9168c65>)((org-data nil (section (:begin 1 :end 148 :contents-b$ 14 org-element-map((org-data nil (section (:begin 1 :end 148 :contents-begin 1 :contents-end 148 :post-blank 0 :po$ 15 org-hugo--get-pre-processed-buffer() 16 org-hugo-export-wim-to-md(:all-subtrees) 17 (save-current-buffer (set-buffer (find-file-noselect org-file)) (message (format "[ox-hugo/export-all file %d/%$ 18 (let ((org-file (car --dolist-tail--))) (save-current-buffer (set-buffer (find-file-noselect org-file)) (messag$ 19 (while --dolist-tail-- (let ((org-file (car --dolist-tail--))) (save-current-buffer (set-buffer (find-file-nose$ 20 (let ((--dolist-tail-- org-files)) (while --dolist-tail-- (let ((org-file (car --dolist-tail--))) (save-current$ 21 (progn (message (format (if dont-recurse "[ox-hugo/export-all] Exporting %d files from %S .."
