Submit extension to markeplace

Hello. Iā€™m trying to submit an extension to the marketplace but I have an issue.
Iā€™m at the step of sending my extension after having generated the certificate and received the certificat from the dev team. Iā€™m now sending my app (using the page https://apps.nextcloud.com/developer/apps/releases/new) but I always has this error ā€œNo possible app folder found. App folder must contain only lowercase ASCII characters or underscoresā€.

Any clue to help me ? All seems ok but this error is persisting.

Thank you for your help :slight_smile:

Hey @Johan_PIQUET,

Is this still an issue?
I downloaded https://www.fajotime.fr/downloads/fajotime_libreofficeviewer.tar.gz and the folder structure looks fine to me at a first sight.
