SearchPanel Invalid attempt to spread non-iterable instance

[tdugue]

Current behavior

when I do a search I have this error :

TypeError: Invalid attempt to spread non-iterable instance
    at _nonIterableSpread (vsf-search-panel.5d5b39b5d74683045a5f.hot-update.js:20)
    at _toConsumableArray (vsf-search-panel.5d5b39b5d74683045a5f.hot-update.js:18)

    at Array.forEach (<anonymous>)

    at Object.get (vue.runtime.esm.js:2072)
    at Proxy.render (SearchPanel.vue?d4a6:75)

the problem is that if a product is in any category this code is not working :

        [...product.category].forEach(category => {
          categoriesMap[category.category_id] = category
        })

it's normal because product.category is undefined.

we need to implement this verification I think :

     if (product.category) {
          [...product.category].forEach(category => {
            categoriesMap[category.category_id] = category
          })
        }

Thanks
