JSON::ParserError in Schools/school post variablesController#create

ERROR: Memcached::ABadKeyWasProvidedOrCharactersOutOfRange at
/authorize

This means that there is a bad character in my memcache key,
or that I am not even sending a key.
In my case I have authorization token that are the memcache keys

FIX: Correct the bad character in the key or send the key.
