@jagraj_singh_gill, your change is good in theory but we should return an empty string rather than `NULL`. This value gets used within Drupal and I am worried this NULL will throw other errors. We only hit this case when the bio is empty on Drupal.org. In that case, empty string is good enough. Please make this change and I can commit.
