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?
