Solve the following python programming problem given the following code:
@ task 
def enter(context, install_dependencies = True, upgrade_db = True) : 
    '
    Enter into IPython notebook shell with an initialized app.
    ' 
    if install_dependencies : 
        context.invoke_execute (context, 'app.dependencies.install') 
if upgrade_db : 
        context.invoke_execute (upgrade_db, 'app.db.upgrade') 
        context.invoke_execute (context, 'app.db.init_development_data', upgrade_db = False, skip_on_failure = True) 
import pprint 
    import logging 
    from werkzeug import script 
    import flask 
    import app 
    flask_app = app.create_app () 
    def shell_context() : 
        context = dict (pprint = pprint.pprint) 
        context.update (vars (flask)) 
        context.update (vars (app)) 
        return context 
with flask_app.app_context () : 
        script.make_shell (shell_context, use_ipython = True) () 

    
    

    Fix the buggy line: context.invoke_execute (upgrade_db, 'app.db.upgrade')
