Error response for Palma de Mallorca Airport (LEPA)

I use FlightXML3 requesting Palma de Mallorca airport (LEPA):
https://{username}:{api-key}@flightxml.flightaware.com/json/FlightXML3/AirportBoards?airport_code=LEPA

The response I get is:
{
“error”: “Invalid value "" for number input.”
}

There is plenty of data in the live version of the homepage:
http://flightaware.com/live/airport/LEPA

Why can I not get data for this airport?

Looks like the airport was missing its elevation which is causing the issue. I’ve updated that airport with elevation data, and when the cached table regenerates it’ll fix this issue.

That is great.
How often does this cache table regenerate?

Thank you!

I believe it’s once or twice a day.
