API call getNftOrderActivitiesByItem No enum constant SELL

[inartin]

When I do this call "getNftOrderActivitiesByItem" with type SELL in parameters, I get this error:

{"status":500,"code":"UNKNOWN","message":"No enum constant com.rarible.protocol.dto.ActivityFilterByItemDto.Types.SELL"}

SELL can be used as a type parameter according to the documentation

Thanks @TheAlexandru

So this is because of incorrect types in apidoc. Should be fixed in the next release. Fixed in master
