The broker scan node has two tuple descriptors: One is dest tuple and the other is src tuple. The src tuple is used to read the lines of the original file, and the dest tuple is used to save the converted lines. The preceding filter is executed on the src tuple, so src tuple descriptor should be used to initialize the filter expression
