Hi All,
For PD2 Super Badge "Aura Component Specialist Task 4" I am getting below error:
"Failed to save BoatSearchForm.cmp: Invalid definition for null:BoatSearchFormController: ApexService.getType() return null with currentNamespace: c, namespace: null, name: BoatSearchFormController: Source"

})

Please suggest remedy.
