I was getting the same error when using the above code. Not sure what the problem is. Here’s what I’m using, which seems to work fine:

add_filter('manage_events_posts_columns' , 'mysite_add_book_columns');

function mysite_add_book_columns( $columns ) {

  $columns = array(
    'cb'           => '<input type="checkbox" />',
    'title'        => 'Title',
    'start_date'   => 'Start Date',
    'end_date'     => 'End Date',
    'location'     => 'Location',
    'categories'   => 'Categories',
    'date'         =>  'Date',
  );
  return $columns;
}

add_action( 'manage_events_posts_custom_column', 'mysite_custom_event_columns', 10, 2 );

function mysite_custom_event_columns( $column ) {

  global $post;

  switch ( $column ) {
    case 'start_date':
      echo get_field( "event_start_date", $post->ID );
      break;

    case 'end_date':
      echo get_field( "event_end_date", $post->ID );
      break;

    case 'location':
      echo get_field( "location", $post->ID );
      break;
  }

}
