You did not tell us which versions of API and TWS/IBGW you use so I can't say for sure. But IBKR refactored the FA concept a little during recent V10 TWS/IBGW versions and support for "profiles" has been removed in 10.22. See the API docs at or the release notes:
The two options you now have for are Groups (faDataType = 1) and Account (faDataType = 3).
