Cucumber Date Field + Random Date + String

Cucumber is throwing the following: error when I am trying to populate a date field within my appian project

This is my Code

Given I populate field "Start Date" with "07/05/2019"
    And I populate field "End Date" with "07/01/2019"
    When I click on button "SUBMIT"

I've tried quite a few methods within cucumber without recourse. Does anyone have any sort of ideas on what I need to be looking for:?

Thanks for the help
