Store files getting undefined when refreshing the browser,

public getStateFile = (): StateFiles => {
return this.store.selectSnapshot(StateFileState).stateFile;};

this is the store operation for getting the state file,

    const stateFile = this.storeOp.getStateFile();

this.ini = this.storeOp.getINIData();
this is the code I am retrieving the state file from the store, it is called in the ngOnInit() lifecycle hook
