New Airport Error with SDK

I am trying to create a new airport where one exists in reality but doesn’t on MSFS. Bathurst NB Canada. CZBF just an empty field on the program… I have downloaded the latest SDK on C drive…and follow the pop up menus to create a new airport, not update and existing one on MSFS…
There doesn’t seem to be any updated videos that follow this new updated SDK>>

I keep getting this error
