error, when a topic cannot be found

[are-txl]

typing texdoc latex-first-aid at the prompt gibes the following error:

...exlive/2026/texmf-dist/scripts/texdoc/texdoclib-view.tlu:24: attempt to index a nil value (local 'docfile')
stack traceback:
...exlive/2026/texmf-dist/scripts/texdoc/texdoclib-view.tlu:24: in upvalue 'view_doc'
...exlive/2026/texmf-dist/scripts/texdoc/texdoclib-view.tlu:334: in function 'texdoclib-view.deliver_results'

/usr/local/texlive/2026/bin/x86_64-linux/texdoc:45: in main chunk

removing the cache file cache-tlpdb.lua does not solve the issue.

thanks

What does texdoc --debug latex-first-aid say on your side?

Seems to be a duplicate of #130, in which I got the same error after responding 1 to "Would you like to search online? (y/N)" prompt.

I found the culprit.
I had 'mode = mixed` in my texdoc.cnf and that triggers the error. Both the default 'view' and 'list' work,
Nevertheless it seems to be a bug, since 'mixed' is documented as a possible value for mode.
