Importing BACPAC file from azure to SQL creating an empty database
I ran into that problem a few minutes and found a way to remove the fulltext stuff from a bacpac.

I found this powershell script (but fixed my backup by hand, because it was faster than trying to understand and use the script)

Rename your backup to zip
extract model.xml and Origin.xml
open model.xml with a text editor and look for "fulltext"
Delete all fulltext elements in the xml
set fulltext to false in the header
Calculate the SHA256 hash of the edited xml (I used hashtab for that)
Fix the hash/checksum in origin.xml
Add the updated files back to the zip
Rename back to bacpac and import
