Submit extension to markeplace

Hello. I’m trying to submit an extension to the marketplace but I have an issue.
I’m at the step of sending my extension after having generated the certificate and received the certificat from the dev team. I’m now sending my app (using the page but I always has this error “No possible app folder found. App folder must contain only lowercase ASCII characters or underscores”.

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 and the folder structure looks fine to me at a first sight.
