DatastoreToBigQuery CREATE_IF_NEEDED problem

[Leon2mb]

Hi,

I'm trying to compile the DatastoreToBigQuery template. But I get this error

An exception occured while executing the Java class. CreateDisposit ion is CREATE_IF_NEEDED, however no schema was provided

I tried to compile the DatastoreToText and TextToBigQuery and both worked, but somehow, from DatastoreToBigQuery isn't working.

Here is the whole Log:
