When trying to click to view a particular order in the Magento 2.3.2 back-end I get a blank page with the following message:

Order View

Information Changes have been made to this section that have not been saved. This tab contains invalid data. Please resolve this before saving.

Screenshot here:

The source code for this page is as follows:

<html><head></head><body><div class="admin__page-nav" data-role="container" id="sales_order_view_tabs">

Having researched this issue I have disabled the Temando_Shipping module as detailed in this question: Cannot View Orders.

Unfortunately this has not resolved the issue.

Investigating further has revealed that this issue may be caused by string truncation as detailed here: https://github.com/magento/magento2/issues/16958

But it is stated that this issue should have been fixed in a previous release.

So far this has only happened on a single order but I am concerned that there may be others if I do not fix the issue.

I should probably point out that this order contains bundle product items, I don't know if that is a cause but as it's something we're starting to use and has been mentioned in connection to a similar issue I thought I should mention it.

In addition the payment method used was a Visa Card passed through SagePay PI integration.

The following error also seems to be appearing in the Apache logs:

AH01071: Got error 'PHP message: PHP Fatal error: Uncaught Error: Call to undefined method Magento\Bundle\Model\Product\Type::getConfigurableAttributeCollection() in /var/www/vhosts/examplewebsite.com/httpdocs/vendor/magento/module-configurable-product/Helper/Product/Options/Loader.php:52\nStack trace:\n#0 /var/www/vhosts/examplewebsite.com/httpdocs/vendor/magento/module-configurable-product/Model/Product/ReadHandler.php(48): Magento\ConfigurableProduct\Helper\Product\Options\Loader->load(Object(Magento\Catalog\Model\Product\Interceptor))\n#1 /var/www/vhosts/examplewebsite.com/httpdocs/vendor/magento/framework/EntityManager/Operation/Read/ReadExtensions.php(48): Magento\ConfigurableProduct\Model\Product\ReadHandler->execute(Object(Magento\Catalog\Model\Product\Interceptor), Array)\n#2 /var/www/vhosts/examplewebsite.com/httpdocs/vendor/magento/framework/EntityManager/Operation/Read.php(112): Magento\Framework\EntityManager\Operation\Read\ReadExtensions->execute(Object(Magento\Catalog\Model\Product\Interceptor), Array)\n#3 /var/www/vhosts/exa...\n', referer:


Can anyone suggest a way to fix this please?

  • Can you please share the payment method of the order you've facing issue with? Also, your magento version.

  • Thanks for responding. The Magento version is given at the start of the question (2.3.2). I have added the payment method (Visa card through Sagepay PI integration) to the question now.

  • Thanks for the info. This issue is occurring for all the orders or any specific order on your website? Have you got any error logs for the same?

  • Hi. Just for a single order at the moment and there is an apache error which seems to happen when I try to access the order. I have added the error into the original question.

You can fix this issue by adding temporary solution adding simple condition in Magento\ConfigurableProduct\Helper\Product\Options\Loader::load(ProductInterface $product) after line no : 51

if (get_class($typeInstance) == 'Magento\Catalog\Model\Product\Type\Simple' || get_class($typeInstance) == 'Magento\Bundle\Model\Product\Type') 
   return null;

Reference: https://github.com/magento/magento2/issues/21663

Hope it helps!!!

    THANK YOU!!! In my case the file in question was located at: vendor > magento > module-configurable-product > Helper > Product > Options > Loader.php But the solution has worked all the same. I'm going to try to work up a custom module so that it doesn't overwrite next time I update but this has definitely got me a lot closer.

  • Perfect... Yes overriding the function in your custom module is a best approach.
