Surcharge Coding error (maybe php8 related)? Caused fatal errors

We noticed on our website that purchases were being correctly transacted into Stripe, however, they were reaching a fatal error on the WordPress side. So although Stripe was capturing the payment, WordPress was showing the user a fatal error, and not re-directing them to the thank-you page. And the orders were not being captured/shown in the WP-admin backend “orders” section.

I did some digging in the error logs and it seemed to be related to “Surchage” coding.
I was getting this error:
Fatal error: Uncaught Error: Cannot use object of type stdClass as array in /public_html/wp-content/plugins/stripe-payments/includes/class-asp-payment-data.php:58

For the moment I have manually updated the code of the plugin myself, editing this file:
/includes/class-asp-payment-data.php

FROM:

public function get_surcharge_data( string $key ) {
        if ( empty($this->surcharge_data) ) {
            $metadata = isset($this->obj->charges->data[0]->metadata) ? $this->obj->charges->data[0]->metadata : array();
            if (isset($metadata['Surcharge Amount'])){
                $this->surcharge_data['amount'] = $metadata['Surcharge Amount'];
            }
            if (isset($metadata['Surcharge Label'])){
                $this->surcharge_data['label'] = $metadata['Surcharge Label'];
            }
        }
        return isset($this->surcharge_data[$key]) ? (string) $this->surcharge_data[$key] : '';
    }

TO:

public function get_surcharge_data( string $key ) {
	// Ensure surcharge_data is initialized as an array if not already
	if (!is_array($this->surcharge_data)) {
		$this->surcharge_data = array();
	}

	if ( empty($this->surcharge_data) ) {
		// Check if metadata exists and is an object
		$metadata = isset($this->obj->charges->data[0]->metadata) ? (array) $this->obj->charges->data[0]->metadata : array();

		if (isset($metadata['Surcharge Amount'])) {
			$this->surcharge_data['amount'] = $metadata['Surcharge Amount'];
		}

		if (isset($metadata['Surcharge Label'])) {
			$this->surcharge_data['label'] = $metadata['Surcharge Label'];
		}
	}

	return isset($this->surcharge_data[$key]) ? (string) $this->surcharge_data[$key] : '';
}

I hope that helps, can you double check if your plugin is setup correctly to handle PHP8 in this regard, or if any other tweaks are necessary?
