Describe the Bug

There are multiple errors reported:

Seems like there can be multiple causes for the same error.

@braddalton The fix linked in this PR will not be implemented as the error has been addressed in #606 which will be included in the next 1.9.0 update. The fix in this PR prevents the error and is an easy change to apply, but version 1.7.0 or this package with the actual fix applied could also be used to prevent the error.

1.7 doesn't work for me. Same error. It displays the popup and shows the credit card fields for 1 second but then closes and shows an error. Logs are the same as i previously published.

@braddalton The error from this issue is unrelated to this message in the popup window from your video. What happens in this window is usually outside of the scope of the plugin. Have you given it a try with a PayPal sandbox account connected to rule out an issue with the merchant account?
If any doubts remain, please open a support request from here: https://paypal.inpsyde.com/docs/request-support/
Thanks!
