Stripe gives fatal error after payment is done

[loppanloppis]

Hi!

First off I'd like to send HUGE thank you's to Todor for providing this amazing crowdfunding extension completely for free. Truly appreciated man! Thank you.

I'm on versions Joomla 3.10.2, running Crowdfunding 2.7.3, Crowdfunding Library 2.7.3 and Stripe Payment plugin 2.4.2.

I'm stuck with an issue receiving Stripe payments. Paypal works fine, also bank transfers.

On Stripe's end, everything seems 100% correct, payment goes through correctly and as far as I can tell, my webhook works fine.

When user returns to my site after payment, instead of seeing the "Thank you" page, the user gets :

Call to a member function getTitle() on null

Digging further in the logs :

Lastly, the com_crowdfunding.payment.php error log tells us :

    'payment_service' => 'stripe',
    'Itemid' => NULL,
  ),
))
'

As far as I can tell, the error appears around when com_crowdfunding tries to create a new transaction in the database. In phpmyadmin I do find the transaction in _crowdf_paymentsession, but it's never transfered to the _crowdf_transactions table. Also, no e-mail is sent out.

Again, the payment reaches Stripe just fine.

I can force the transaction to go through if I comment out some lines in TransactionObserver.php but this is probably not a good solution, and although I managed to get a correct entry in the _crowdf_transactions table, and an e-mail going out to the backer that way, the same error message was still shown in the backend. Also I'm not sure how this "solution" affects other areas.

I'm truly stuck here, and truly grateful for advice! Thank you :).

Best regards

Peter
