I want to test create a custom connector in a Power App that connects to table in Databricks.  

The issue is if I have any columns like int or bigint. 

No matter what I define in the response in my swagger definition See  below), it is not correct type in the Power App so cannot be displayed. string columns are displayed ok.

testint:
type: number
testint:
type: integer
format: int64
testint:
type: string
