Product comparison page displaying console error "error in dispatch"

[tiago-freire]

I followed all vtex.product-comparison config steps and search page, category page, product page and bucket area for products to compare are working fine. Just only the product-comparison page is not working (blank page), giving me console error error in dispatch {args: {…}, type: 'SET_SHOW_DIFFERENCES'}. I created a "store.custom#product-comparison-list" block following this step and the properly route to product-comparison.

I've already reviewed all the settings and I'm trying to debug through app link, which I cloned in the version I'm using.

I think some undocumented step is missing.
