I am on Magento 2.2.5 and when going to Sales > Orders > View on the backend I receive the following message:
Looking at the error log I see the following:
05-Jul-2018 17:13:52 UTC] PHP Fatal error: Uncaught Error: Call to a member function getExtOrderId() on null in /home/passionh/public_html/vendor/temando/module-shipping-m2/view/adminhtml/templates/sales/order/view/info.phtml:134 Stack trace: #0 /home/passionh/public_html/vendor/magento/framework/View/TemplateEngine/Php.php(59): include() #1 /home/passionh/public_html/vendor/magento/framework/View/Element/Template.php(270): Magento\Framework\View\TemplateEngine\Php->render(Object(Temando\Shipping\Block\Adminhtml\Sales\Order\View\Info\Interceptor), '/home/passionh/...', Array) #2 /home/passionh/public_html/generated/code/Temando/Shipping/Block/Adminhtml/Sales/Order/View/Info/Interceptor.php(544): Magento\Framework\View\Element\Template->fetchView('/home/passionh/...') #3 /home/passionh/public_html/vendor/magento/framework/View/Element/Template.php(300): Temando\Shipping\Block\Adminhtml\Sales\Order\View\Info\Interceptor->fetchView('/home/passionh/...') #4 /home/passionh/public_html/vendor/magento/module-backend/Block/Template.php(124): Magento\Framework in /home/passionh/public_html/vendor/temando/module-shipping-m2/view/adminhtml/templates/sales/order/view/info.phtml on line 134
Unfortunately I have very little experience with any of this so desperately need some advice to fix the error.
Try to disable temando shipping module and check it
I have disabled Temando as you suggested and I am able to view the order details page now, however why would an error like this occur? It is a module supplied with Magento 2.2.5...I am confused.
maybe it is old order, and you are checking after upgrade Magento.
If any solution help you then give kudos or mark as solution
That's the issue, it is not an old order. I did think that, so I put through another order and still experienced the issue. Disabling the module allows me to access the order details page, but it doesn't solve the issue at hand. Any suggestions on what it may be? or could it be a bug with Magento 2.2.5? Kudos for your recommendation though.
first make sure below thing
sales_order contain ext_order_id column
if not then the issue is related to module install
Sorry, but where do I find "sales_order contain ext_order_id column"?
Sales order does contain a column ext_order_id however the values on each row are NULL.
Off topic question for you - does database need to be updated after upgrade from Magento 2.2.4 to 2.2.5? If so, how do I do it? I am using cPanel and have SSH access for command line.
