Case Converter: "No column spec compatible to 'DocumentValue'

I’m trying to do something relatively straightforward – I’d like to upcase all of my data from a CSV file prior to staging in a database. I’m trying to use the “Case Converter” node, but I get the following error:

Case Converter: "No column spec compatible to 'DocumentValue'

The previous node in the chain is a Columne Rename node which displays the correct table on output.

Hi @judwig79 ,

There are (confusingly) two Case Converter nodes

I think you probably want the one I’ve highlighted in red if you are using standard String data.
