# Bugs and Feature Requests

You can report bugs and feature requests to the Istio team in one of three places:

- [Product Bugs and Feature Requests](https://github.com/istio/istio/issues)
- [Documentation Bugs and Feature Requests](https://github.com/istio/istio.io/issues)
- [Community and Governance Issues](https://github.com/istio/community/issues)

For security vulnerabilities, please don't report a bug (which is public) and instead follow

    assertThat(statusLine.code).isEqualTo(code)
  }

We are going to include this `APIRouter` in the main `FastAPI` app, but first, let's check the dependencies and another `APIRouter`.

## Dependencies

We see that we are going to need some dependencies used in several places of the application.

So we put them in their own `dependencies` module (`app/dependencies.py`).

We will now use a simple dependency to read a custom `X-Token` header:

//// tab | Python 3.9+

   *
   * @since 8.0
   */
  public static final byte BEL = 7;

  /**
   * Backspace ('\b'): A format effector which controls the movement of the printing position one
   * printing space backward on the same printing line. (Applicable also to display devices.)
   *
   * @since 8.0
   */
  public static final byte BS = 8;

  /**

* Takes a `first_name` and `last_name`.
* Converts the first letter of each one to upper case with `title()`.
* <abbr title="Puts them together, as one. With the contents of one after the other.">Concatenates</abbr> them with a space in the middle.

### Edit it

It's a very simple program.

But now imagine that you were writing it from scratch.
