Description

Our service call expects a array/list of integers as parameter. The thrift service definition looks like:
list<StatisticData> statistic_of_cars(1: list<i32> ids)

When we call this service with an empty list, we get an EOFError:
>> c.statistic_of_cars([])
EOFError: end of file reached

Every following service call cannot be executed and throws the same exception. The service fails even if we call it with a non empty array/list.
