[Lychee] blank photos?



My YunoHost server

Hardware: Raspberry Pi at home
YunoHost version: 11.1.19
I have access to my server : Through SSH | through the webadmin
Are you in a special context or did you perform some particular tweaking on your YunoHost instance ? : no
If your request is related to an app, specify its name and version: lychee v4.8.0~ynh1

Description of my issue


I installed Lychee to try out and it’s promising but I have a major issue in that Lychee does not display any photo…

Expected behavior
Uploaded photos are shown

Actual behavior
Uploaded photos show as blank frames (with the right ratio, see appendix). On mobile, the format of the photo is written in the top left corner (thumbnail, small, medium, big, …). Opening original photo redirects to a 403 error page (although this may be due to a lychee config I haven’t set), but download works well.

Steps to reproduce
Install lychee and upload a photo.

Any idea? Thanks for all your help (and for the amazing work you do, I love my Yuno!)

Description du problème

Salut !

J’ai installé Lychee pour essayer et ça a l’air top mais il y a un problème majeur qui est que Lychee n’affiche aucune photo…

Comportement attendu
Les photos uploadées sont affichées

Comportement obtenu
Les photos uploadées sont des cadres vides (de la bonne proportion, voir l’annexe). Sur mobile, le format de la photo is est indiqué dans le coin supérieur gauche (thumbnail, small, medium, big, …). Ouvrir la photo originale redirige sur une page d’erreur 403 (mais c’est peut être une config Lychee que je n’ai pas faite), mais le téléchargement fonctionne bien.

Étapes pour reproduire
Installer Lychee et uploader une photo.

Une idée ? Merci pour votre aide (et pour le super boulot, Yuno c’est le feu!)

can you try
chmod -R 755 /home/yunohost.app/lychee/
on a terminal?

Yes that fixes it! Awesome thanks. Did I miss some step that explained the command has to be run?
