I am getting a type error in my reducers' file that my Property 'address' does not exist on type 'number | { connection: boolean; address: string; }'. I am using redux with typescript in my react application. I know it is due to the incorrect typesetting but I can't figure out how. I am using typescript with redux the first time and got stuck in this
Here is my actions file.

interface IMetaMaskConnection{
    type:typeof ActionType.CONNECT_META_MASK,
     payload:{
       connection:boolean,
       address:string
     }
}
interface IHourPassed{
  type:typeof ActionType.HOUR_PASSED,
  payload:number
}


export type Action = IMetaMaskConnection | IHourPassed 

export const connectMetaMaskAction = (data:IMetaMaskConnection['payload']):Action => ({
  type: ActionType.CONNECT_META_MASK,
 payload:data
});
export const setHourPassed = (data:IHourPassed['payload']):Action => ({
  type: ActionType.HOUR_PASSED,
 payload:data
});

export const reducer= (state:IState=initialState, action:Action):IState=> {
    const {type, payload}=action;
    switch(type){
        case ActionType.CONNECT_META_MASK:
        return {
        ...state,
        address:payload.address,
        connection:payload.connection
        } 
        case ActionType.HOUR_PASSED:
        return {
        ...state,
        hourPassed:payload
        } 
        
         default:
      return state;
    }
}
export type State= ReturnType<typeof reducer>

This is my error screenshot.
