When viewing product only the image shows

[SamB-GB]

Upgraded to 2.3.2 and now when viewing a product only the product image shows and the following PHP error is generated.

[27-Jun-2019 01:14:57 UTC] PHP Fatal error: Uncaught Error: Call to a member function getOptionsJson() on null in /chroot/home/a06150d0/magento_root/vendor/magento/module-catalog/view/frontend/templates/product/view/gallery.phtml:48

I have the same issue:

Basically the code for some reason in the product/view/gallery.phtml expects $block->getGalleryOptions() to always be an object - in this instance it returns null and the result call of getOptionsJson() is causing an exception which kills the script from continuing hence why just the image appears (thou all the header is included if you view source) is returned.

<script type="text/x-magento-init"> { "[data-gallery-role=gallery-placeholder]": { "mage/gallery/gallery": { "mixins":["magnifier/magnify"], "magnifierOpts": <?= /* @escapeNotVerified */ $block->getMagnifier() ?>, "data": <?= /* @escapeNotVerified */ $block->getGalleryImagesJson() ?>, "options": <?= /* @noEscape */ $block->getGalleryOptions()->getOptionsJson() ?>, "fullscreen": <?= /* @noEscape */ $block->getGalleryOptions()->getFSOptionsJson() ?>, "breakpoints": <?= /* @escapeNotVerified */ $block->getBreakpoints() ?> } } } </script>

I'm running Magento 2.3.2 on PHP 7.1.30 on Cpanel CENTOS 6.10 v78.0.23.

I don't have a vanilla install to try it on but if I remove that call and leave the options blank - the page loads correctly.

My product only has a single image - adding more images does not cause the issue to go away so it is not dependent upon how many images you have on the product.

A temporary workaround is to override module-catalog/view/frontend/templates/product/view/gallery.phtml file on your theme from Magento 2.3.1. Works for me.

[SamB-GB]

Thing is it was working fine in 2.3.1 with no changes required this end.

Getting the same error. Help Needed ASAP.

[raghuiamsingh]

To solve this you can override Magento\Catalog\Block\Product\View\Gallery and add a new function getGalleryOptions(). This function should return an instance of Magento\Catalog\Block\Product\View\GalleryOptions, the instance should be injected to the overridden class file.

[hostep]

If you've instantiated the Magento\Catalog\Block\Product\View\Gallery block in your custom theme in some xml file, make sure you add that new gallery_options argument.
See here for how it was changed in 2.3.2: https://github.com/magento/magento2/pull/18440/files#diff-85a7317671ca24ca85af5cb5808b676e (app/code/Magento/Catalog/view/frontend/layout/catalog_product_view.xml file)

Not sure if this is helpful here, but I just saw that change by accident and I think it is related.

[gwharton]

Yes, this is a change I made in one of my PR's. The key is to make sure that the argument gallery_options is injected as an argument to the Gallery Block class in the layout xml. Its not the way I originally wanted to implement it, I wanted to add the getOptionsJson() functions directly to the Magento\Catalog\Block\Product\View\Gallery class, but was blocked from doing so due to backwards compatability rules.

What I don't understand is why some of you have the new Magento\Catalog\Block\Product\View\Gallery class with the $block->getGalleryOptions()->getOptionsJson() call, but don't have the associated change in catalog_product_view.xml. Is it because you are inheriting from, or instantiating Magento\Catalog\Block\Product\View\Gallery in your own class/theme, and haven't injected gallery_options at your layout xml/class level.

With hindsight, it would have been prudent to add a comment block to the top of Magento\Catalog\Block\Product\View\Gallery stating that you must inject gallery_options as argument, otherwise, how would you know? Perhaps this bug could morph into a documentation update for the Gallery class.

[alexjuniodev]

I didn't get how should I override the file module-catalog/view/frontend/templates/product/view/gallery.phtml. Could some of you guys help me?

[gwharton]

@alexjuniodev Don't do that.

You need to locate in whichever of your third party modules is instantiating an instance of the "\Magento\Catalog\Block\Product\View\Gallery" class in its layout xml files and ensure it is injecting the argument "gallery_options" to the block as per the below code.

https://github.com/gwharton/magento2/blob/e29fa3d9b150d81da1caa3484d90ecc3d2156770/app/code/Magento/Catalog/view/frontend/layout/catalog_product_view.xml#L124-L128

Or contact your theme/module providers and get them to update their theme/module to the latest magento version.

The above referenced PR's could also be used as a workaround/alternative solution, but it is unclear at the moment if the above PR's will be accepted into Magento or not. However they would give you a working system without delving into your module/themes code.
