Passing Data from Activity to Fragment

My app has a main activity with a navigation drawer that has several fragments. In one fragment, I want the user in input some information and press a button which navigates them to an activity. The user will enter information within the activity and press a button to return back to the fragment with their information saved. Essentially, I want to pass data from the activity to the fragment. I have created a bundle to pass the data, but I am getting a null pointer exception when I click on the fragment in the navigation drawer. It won't even open Any thoughts?

Java
 //The button in the activity to pass data
                                    @Override
                                    public void onClick(View view) {

                                        Bundle objectId = new Bundle();
                                        objectId.putString(Worker.KEY_WORKER_OBJECTID, mPayload);
                                        StartWorkFragment passId = new StartWorkFragment();
                                        passId.setArguments(objectId);
                                        finish();


                                    }
                                });

Java
//Fragment where I am trying to receive the passed data from the Activity
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {

        View rootView = inflater.inflate(R.layout.fragment_start_work_tag, container, false);

        mIdTestView = (TextView) rootView.findViewById(R.id.testing_worker_id_pass);
        mTagObjectId = this.getArguments().getString(Worker.KEY_WORKER_OBJECTID);
        mIdTestView.setText(mTagObjectId);

        return rootView;

    }
}
