When opening a variable product page, a WooCommerce error message about adding to the cart is displayed.

Describe the Bug

WooCommerce PayPal Payments 4.0.3 displays an error when opening a variable product page, which in previous versions was still being generated in the code but was hidden as a WooCommerce notice (not shown to the user).

To Reproduce

• Plugins:
  • WooCommerce 10.7.0
  • WooPayments 10.7.1
  • WooCommerce PayPal Payments 4.0.3
• Enable the PayPal payment gateway.
• Create a variable product with at least two options
• Open the product page on the frontend - an error will appear

Screenshots

It is triggered in every version of WooCommerce PayPal Payments 4.0.x that I tested.

It triggers execution of the code that produces this exception (which is later converted into a WooCommerce notice).

Expected Behavior

• Not generating the notice or hiding it.

Actual Behavior

• The notice is generated, but in previous versions it was being hidden.

Environment

Plugins:

• WooCommerce 10.7.0
• WooPayments 10.7.1
• WooCommerce PayPal Payments 4.0.3

Additional Details

I can see that between 4.0.2 and 4.0.3 you modified something in the notification hiding system - it’s likely that this is why it stopped working for this case.

• 4.0.2...4.0.3#diff-cb3efde99f2cb70e0bef7faf63bcc0840fdae99c913eab5f29d6c502f5a84bac
