   ### Superset version
   master branch
   
   ### Expected results
   follow the sample from flask app builder example:
   https://github.com/dpgaspar/Flask-AppBuilder/tree/master/examples/quickfiles
   
   I tried to use a F.A.B project, it worked fine, but in superset, it failed.
   
   ### Actual results
   when inserting database, it got null for file column, the errors like below:
