Not working on bestbuy ca website

I got stuck during the initialization on the bestbuy ca website. I replace every bestbuy.com to bestbuy.ca and got this :
userscript.html?name=BestBuy-RefreshNoBot.user.js&id=d54d7d78-833a-4f32-ae85-3d1294716afc:743 Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'length')

Start with BestBuy-RefreshNoBot.user.js at the reported failure around line 743 and reproduce initialization on bestbuy.ca after the documented domain replacements. Trace the undefined value involved in the length access and compare the Canadian-site behavior with bestbuy.com. Done means initialization completes without the reported TypeError on bestbuy.ca.
