Android Studio Injecting to another application requires INJECT_EVENTS permission

Hi I am testing for adding a new item to a class (Recipe). Everything is okay until it tries to perform the The main parts of the error message I can determine are:

androidx.test.espresso.PerformException: Error performing 'single click - At Coordinates: 539, 1647 and precision: 16, 16' on view 'with id: uk.edu.le.co2103.myrecipebook:id/button_save'.

and then

Caused by: androidx.test.espresso.PerformException: Error performing 'Send down motion event' on view 'unknown'.

and finally

Caused by: androidx.test.espresso.InjectEventSecurityException: java.lang.SecurityException: Injecting to another application requires INJECT_EVENTS permission

My testing code is as follows

@RunWith(AndroidJUnit4.class)
 public class MyRecipeBookEspressoTest {
private String Name;
private String Ing;
private String Method;

@Rule
public ActivityTestRule<MainActivity> mainActivityActivityTestRule =
        new ActivityTestRule<>(MainActivity.class);

@Test
public void testAddNewRecipe() {
    onView(withId(R.id.fab)).perform(click());
    onView(withId(R.id.edit_recipe1))
            .perform(new TypeTextAction("test Name"));
    onView(withId(R.id.edit_recipe2))
            .perform(new TypeTextAction("test iNG"));
    onView(withId(R.id.edit_recipe3))
            .perform(new TypeTextAction("test Method"));
    onView(withId(R.id.button_save)).perform(click());
    fail("Implement this test");
}
