I have installed on the web the English language and the Spanish
If active the English language, the map works well, gives me the route to the destination
The problem is that if I activate the Spanish language, telling that calculates the route gives me ZERO_RESULTS
Zero result - it is not find string. Ie you enter text address and map geocoder doesn't find it.
May be you restrict map by region, or something else. Without link to map and what you pass to find I can't tell more.
I suggest enable autocomplete feature (read my docs), it is easy and you will not get zero result (mostly your string will be completed)
