The export of the catalog crashes when a bundle does not have a "Is Default" item

[xaviermarchegay]

When a bundle does not have a "Is Default" item, we keep hitting the "continue" line 798.

plugin-magento2/Model/Export/Product.php

Lines 795 to 804 in b4c7416

	if (count($optionIds) > 1) {
	foreach ($selectionCollection as $selection) {
	if (!$selection->getIsDefault()) {
	continue;
	}
	$bundleOptions[$selection->getOptionId()][] = [
	'product_id' => (int) $selection->getProductId(),
	'default_qty' => (int) $selection->getSelectionQty()
	];
	}

Then $bundleOptions ends up being an empty array.

That means that $quantities remains being an empty array.

plugin-magento2/Model/Export/Product.php

Lines 755 to 766 in b4c7416

	$quantities = [];
	$bundleOptions = $this->getBundleOptionsProductIds($this->product);
	foreach ($bundleOptions as $option) {
	foreach ($option as $dataProduct) {
	$productId = $dataProduct['product_id'];
	$defaultQty = ($dataProduct['default_qty'] > 0) ? $dataProduct['default_qty'] : 1;
	$stockQty = $this->stockRegistry->getStockItem($productId, $this->store->getId())->getQty();
	$quantities[$productId] = floor($stockQty / $defaultQty);
	}
	}
	return min($quantities) > 0 ? (int) min($quantities) : 0;;

And finally the "min" line 766 crashes because it is not allowed.

min(): Argument #1 ($value) must contain at least one element
