When you use connection parameters in REST connection profile definition, the resulting transformation SQL generated during import from this CP is malformed.

ViewModel.getCases.query AS query, || '/' || ViewModel.getCases.query ViewModel.getCases.newSearch AS newSearch || '/' || ViewModel.getCases.newSearch

SQL without the bold/underlined parts works. (I mean underlined/bold parts in this bug Description, not in screenshot)
See attached screenshots
