Call to a member function getMetaTitle() on null

I have been trying to export our product catalog from the Admin panel, but it fails every time.

 

Checking the error_log I see the following:

[19-Nov-2020 14:32:42 UTC] PHP Fatal error:  Uncaught Error: Call to a member function getMetaTitle() on null in /home/devmoore/public_html/vendor/magento/module-catalog/Block/Product/Gallery.php:54
Stack trace:
#0 /home/devmoore/public_html/vendor/magento/framework/View/Element/AbstractBlock.php(285): Magento\Catalog\Block\Product\Gallery->_prepareLayout()

#4 /home/dev in /home/devmoore/public_html/vendor/magento/module-catalog/Block/Product/Gallery.php on line 54

I have checked the files listed and they all appear to be un-edited. The website still loads fine and no errors seem visible on the frontend.

 

Any idea what might cause this? The only changes that have been made to the site recently are to apply a patch to fix the date issue on PDF invoices. This was applied using composer, could something have broken related to this?

Re: Call to a member function getMetaTitle() on null

@Daniel_Moores ,

the issue should be there 
kindly check var/report folder if there any new files created for error 

find var/report -mmin -10

this will give you files created within last 10 mins 

 

also kindly watch logs using the tail command 

tail -f var/log/*.log

and try to export 

it will show you on the screen in case of any exception error.

@amitsamsukha thanks for the reply.

 

Nothing appears to be generated in the var/report folder.

 

[2020-11-20 13:16:55] main.CRITICAL: Notice: Undefined offset: 103 in /home/devmoore/public_html/vendor/magento/module-catalog-import-export/Model/Export/Product.php on line 1085 {"exception":"[object] (Exception(code: 0): Notice: Undefined offset: 103 in /home/devmoore/public_html/vendor/magento/module-catalog-import-export/Model/Export/Product.php on line 1085 at /home/devmoore/public_html/vendor/magento/framework/App/ErrorHandler.php:61)"} []

I have found online that the offset is the attribute. 103 is meta_title.

 

I had done some editing of attribute sets previously, so not sure if it's related to that.
