"""
    An HTTP exception you can raise in your own code to show errors to the client.

    This is for client errors, invalid authentication, invalid data, etc. Not for server
    errors in your code.

    Read more about it in the
    [FastAPI docs for Handling Errors](https://fastapi.tiangolo.com/tutorial/handling-errors/).

    ## Example

    ```python

		w, err := strconv.Atoi(ws)
		if err != nil {
			return cfg, fmt.Errorf("'heal:drive_workers' value invalid: %w", err)
		}
		if w < 1 {
			return cfg, fmt.Errorf("'heal:drive_workers' value invalid: zero or negative integer unsupported")
