Hi,

This is a very typical error when you have accidentally passed a String
instead of a Stream.
... which you did here:
> stream := workingDir/myFileName readStreamDo: [ :stream | stream
contents].
You can either operate directly on the file stream, e.g.
file := 'D:\tmp\rules.csv' asFileReference.
result := file readStreamDo: [ :stream | |reader|
reader := NeoCSVReader new.
reader on: stream.
reader upToEnd.
].
Or if you already have a string, then ask it for its readStream
file := 'D:\tmp\rules.csv' asFileReference.
contents := file contents.
reader := NeoCSVReader new.
reader on: contents readStream.
reader upToEnd.
