Have you tried using jdump?

Jdump allows you to dump variables without exiting, they show in a popup in the browser on the next page load. So you can see variables from page load and submit.

Thanks, now i can see that the stripe plugin is collecting the data from the form before saving to the database, there is nothing to collect, all Strings are empty.
Is it possible that the Plugin collects the data after submitting the form to the database.
Because thats the moment where i can calculate the costs for this subscription.
