Attempted to assign to readonly property Error when using redux

my slice and reducer :

import { createSlice } from '@reduxjs/toolkit'

export const TransactionsListSlice = createSlice({
  name: 'transactions_list',
  initialState: {
    value: []
  },
  reducers: {
    saveTransactionsList: (state, action) => {
      state.value = action.payload
    }
  }
})

export const { saveTransactionsList } = TransactionsListSlice.actions

export default TransactionsListSlice.reducer

let transactions_list = useSelector(state => state.transactions_list.value);
