Invalid OS Property payment plugin

Hi! Trying to develop a payment plugin for a customer I'm getting Invalid OS Property payment plugin at install time. I've followed the instructions at osproperty.ext4joomla.com/documentation/...op-osproperty-plugin

Any ideas why?

Thanks!

EDIT1: If I compress stripe original payment plugin files and try to reinstall it, I get the same error message Invalid OS Property payment plugin

EDIT2: OS Property Version 2.9.8, Joomla 3.7.2
