Possibly the object is 'null'

I'm getting the following Typescript errors in my code
I'm getting these parameters from a previous screen. As in the example of the react nativigation documentation.https://reactnavigation.org/docs/params/

interface PixChargeAmountProps {  route?: string;}const Amount: React.FC<PixChargeAmountProps> = ({ route }) => {const { trackOriginFlow } = route.params;}

console.log(route) ->

"params": {"trackOriginFlow": "ACTIVITIES_SCREEN_BUTTON"}, "path": undefined}

I get the following errors from route.params

route = Possibly the object is 'null'

params = Property 'params' does not exist in type 'string'
