This is very specific error but can happen in some scenerios. When my product name/label starts with "0" (and it does happen often when SKU is used for label as in #1940664: Allow SKU in autocomplete reference widget) and start typing "0..." this gets interpreted as empty in inline_entity_form_autocomplete and therefore MENU_ACCESS_DENIED is returned as result.
