All tests passed in package_check but resulted a level 0

summary

Soapbox_ynh passes all tests, somehow package_check mark it as broken. Why this happens?

It may be that it’s level 0 because the app is not yet in the catalog. If you check the very beginning of the log, there may be an error reported in the package linter … (though agreed that it’s confusing to see ‘OK’ for package linter in the summary :P)
