Custom transformer propagating more attributes than desired

I have defined a custom transformer, and it is outputting more attributes than what I want. I just want to output these two attributes (network_id and lower_network_id):

 

But when using it in the main workbench, it is also outputting attributes from the original input features:

 

I assume this is is because they automatically propagate all source attributes forward, but I want to avoid this, I just want the two-column list. How can I achieve this?

Try inserting the AttributeKeeper before the output port to keep only required attribute.

Why not inspect features with Visual/Data Preview and Feature/Record Information before writing them into a destination dataset?
