Not compatible with Elementor :(

[geofry93]

After lots of testing and disabling of plugins and themes, I've discovered that the cause of the error is an incompatibility with elementor and WooCommerce Blocks. I'm using WooCommerce Blocks to display my checkout page and the issue is that after submitting a purchase, I do not get redirected to the order confirmation page. Here is what the error message looks like:

Fatal error: Uncaught Error: Call to undefined method WP_Error::get_data() in /home/customer/www/staging4.harrym7.sg-host.com/public_html/wp-content/plugins/woo-gutenberg-products-block/src/RestApi.php:64 Stack trace: #0 /home/customer/www/staging4.harrym7.sg-host.com/public_html/wp-content/plugins/woo-gutenberg-products-block/src/BlockTypes/AbstractBlock.php(349): Automattic\WooCommerce\Blocks\RestApi->get_routes_from_namespace('wc/store') #12058 /home/customer/www/staging4.harrym7.sg-host.com/public_html/wp-content/plugins/woo-gutenberg-products-block/src/BlockTypes/Checkout.php(99): Automattic\WooCommerce\Blocks\BlockTypes\AbstractBlock->enqueue_data(Array) #2 /home/customer/www/staging4.harrym7.sg-host.com/public_html/wp-content/plugins/woo-gutenberg-products-block/src/BlockTypes/AbstractBlock.php(287): Automattic\WooCommerce\Blocks\BlockTypes\Checkout->enqueue_data(Array) #3 /home/customer/www/staging4.harrym7.sg-host.com/public_html/wp-content/plugins/woo-gutenberg-products-block/src/BlockTypes/Checkout.php(55): Automat in /home/customer/www/staging4.harrym7.sg-host.com/public_html/wp-content/plugins/woo-gutenberg-products-block/src/RestApi.php on line 64
There has been a critical error on this website.

Here's what happens when I complete an order with Elementor enabled (no order summary shows)

Here is what happens when I disable Elementor (order summary shows!)

Thanks!

Hi @geofry93, thanks for taking time to debug this, determine the conflict with Elementor and then create this issue.

While there is clearly a fatal happening in the call stack within WooCommerce blocks, I suspect the trigger for the fatal likely has something to do with loading order in Elementor because the error is pointing to a low level route getter within the Store REST API.

I've created #4683 to at least improve the error handling here and keep the fatal from happening in these contexts, but even then I don't think fixing it will address the issue with the Order Received page not loading correctly in the Elementor context. Ultimately, this is something for the Elementor team to investigate and troubleshoot.
