Why am I seeing a liquid error on my Warehouse 4.0 theme search page?

[lierre-ca]

We are using the theme Warehouse 4.0 and noticed an issue on the search result page.

When we type in a brand name or a product name in the search bar, the result page shows the related products followed by: 

“Liquid error (snippets/product-item line 296): product form must be given a product” 

However, the issue doesn't occur on my colleagues' devices, it only shows on my computer.

Anyone knows how to fix it or what I might’ve done.
