[Bug]: Error handling on "Get data from XML" does not work

What happened?

We have a use case where REST API sends XML data, which we need to parse and map data to database tables.

We use "Get data from XML" to parse the source data, which sometimes gets aborted with errors like

org.dom4j.DocumentException: Error on line -1 of document : Premature end of file.

The error handling route on the transform does not get activated, preventing the activation of transforms like write to log, etc. to log the actual bad xml data which caused the issue in first place.

Expectation:
When the error handling route is added on the XML transform and the transform fails, the data should flow through that route and subsequent transforms for error handling should be activated

This looks like there's an error in the file structure that is thrown before row processing (and the error handling per row) kicks in.
Is the XML result that is returned by your REST API call valid XML? Since you're receiving this as an XML field, we could probably use the input row to throw an error in the error handling hops, but that wouldn't work for similar problems in standalone XML files.
