Phoca Cart checkout error after update to J5

[RolandLaich]

Hi - I am a webdesigner and a customer of mine uses Phoca Cart with J4. After updating anything to J5 all worked fine except the checkout failing with an error as follows:
Joomla\CMS\Event\Model\FormEvent::onSetData(): Argument #1 ($value) must be of type object|array, false given, called in /path/to/libraries/src/Event/AbstractEvent.php on line 227
In the forum I found some info about Phoca Cart for J5 is currently beta.
Could you please tell the schedule for full compatibility of Phoca Cart with J5?
Best regards, Roland

Although it says that there is a beta version, Phoca Cart is compatible and works with Joomla 5. Only some small details related to E-mail templates are left to release the stable version.

As nidzo wrote, Phoca Cart 5 is fully compatible with Joomla 5. Please enable debug mode and past here the whole error message so we know from where the error is coming. It looks like Joomla issue.

Thank you, Jan
