LearnPress and Uncaught Error after update

[iworks]

Hi! I noticed the problem after update the Omnibus plugin to newest version (3.0.3).

I see the error: PHP Fatal error: Uncaught Error: Call to a member function has_sale_price() on bool in /public_html/wp-content/plugins/omnibus/includes/iworks/omnibus/integration/class-iworks-omnibus-integration-learnpress.php:63

I have installed the learnpress plugin (also the newest version – 4.2.7.4).
When I made the downgrade of Omnibus plugin to 3.0.0 – this error is not showing.

Could you verify this issue? I want to update your plugin to the newest version, but in such a situation I cannot.

Thanks in advance!
