Link shared Mindmap leads to Internal Server error (0.0.22, NC 18.0.6)

[timm2k]

Hi @ACTom,

I can't open shared links which points directly to a Mindmap file. Opening such links lead to Internal Server errros.

message":"Exception":"TypeError"
"Message":"substr() expects parameter 3 to be int, bool given"
"Code":0
"Trace":{\"file\":\"/var/www/html/nextcloud/lib/private/Files/Type/Detection.php\",\"line\":377,\"function\":\"substr\",\"args\":[\"mindmap\",0,false]},{\"file\":\"/var/www/html/nextcloud/apps/files_sharing/templates/public.php\",\"line\":22,\"function\":\"mimeTypeIcon\",\"class\":\"OC\\\\Files\\\\Type\\\\Detection\",\"type\":\"->\",\"args\":[\"mindmap\"]},{\"file\":\"/var/www/html/nextcloud/lib/private/Template/Base.php\",\"line\":179,\"args\":[\"/var/www/html/nextcloud/apps/files_sharing/templates/public.php\"],\"function\":\"include\"},{\"file\":\"/var/www/html/nextcloud/lib/private/Template/Base.php\",\"line\":151,\"function\":\"load\",\"class\":\"OC\\\\Template\\\\Base\"
...

I think the mime type detection doesn't work well in 0.0.22 with Nextcloud 18.0.6

I didn't get this error with NC 19.

Can you please fix this?

Kind regards

Timm

okay, after digging deeper into this the solution is quite easy: nextcloud/core/img/filetypes/mindmap.svg is missing. This is no problem for NC19 but for NC18 it is.

Workaround:
cp nextcloud/apps/files_mindmap/img/mindmap.svg nextcloud/core/img/filetypes/mindmap.svg

This helped me!! I needed it although I have NC 19

Same in NC 19.0.3 (upgraded from previous version). Will it be patched in next version of NC?
