action.payload in redux-tookit issue

Question

i'm developing login authentication using BarCodeScanner from expo, so i'm trying to take the data from the QR code and send it to redux to change the state to authenticated or not, here is my state,

 const initialState ={
        usersList:["u125585212" , "u25487665542" , "u87sujdjk8554"],
        authenticated : false ,
        scannedNumber: false,
    }; 

and the reducers,

reducers:{
        authenticatedOperation :(state,action)=>{
         if(state.usersList.indexOf(action.payload) !== -1){
            state.authenticated  = true ; 
           }else if(state.usersList.indexOf(action.payload) === -1){
            state.authenticated  = false ; 
           }
       }

it always show me the result is -1 even if it's in my state i tried to dispatch any number from the array and it's worked but when i use action.payload is appear if i make console.log(action.payload) but if use for example

    state.usersList.indexOf(action.payload) // the return -1 always
state.usersList.includes(action.payload) // the return false always

any help please ......
