Has anyone ever had luck pulling down a form for a custom transaction type? Any suggestions? It's currently not finding the id of the form whenever I try to search it with SDF. I need the form for a saved CSV import I want to migrate to production. I tried doing this through the VSCode plugin and the Node command line tool with little luck.

SDF does *not* support Custom Transaction Type forms. It gave a me a headache, too. In reality, stay away from Custom Transaction Types whenever possible. There are more limits than features.
