If I don't do the flatmapelements method it performs as the java code. Only the flatmapelements produce errors.

Show us the stacktrace of the exception
@marlin The java version that only splits the string works?
m
Yes
a
You could try the following: 
.via(SerializableFunction : { word: String -> word.split(" ") })
what is the type of 
lines
?
m
PCollection<String!>!
a
is it possible that 
lines
contains `null`s?
m
no...
a
does it happen during the creation of 
FlatMapElements
or when it is actually applied to 
lines
?
