Not clear which app is declaring the custom permission. In any case it needs to
be installed first, the system cannot grant you a permission it
doesn't know about,
hence the exception. If it's pre-installed, the permission is added to
the database
(packages.xml) at first boot. If not, it's added when it's installed.
Pull packages.xml
to confirm.

Protection-level and signing certificate do not matter here.
