You could also define it as a normal function instead of `async def`:

By returning the result of calling `generate_html_response()`, you are already returning a `Response` that will override the default **FastAPI** behavior.

But as you passed the `HTMLResponse` in the `response_class` too, **FastAPI** will know how to document it in OpenAPI and the interactive docs as HTML with `text/html`:

## Available responses { #available-responses }

        throwUnchecked(); // This compiles without try-catch
    }

    private void throwUnchecked() {
        if (Math.random() > 1) { // Never true, but compiler doesn't know
            throw new CrawlerSystemException("Unchecked");
        }
    }

    /**

    public void test_suppressedExceptions() throws Exception {

Using Linux containers has several advantages including **security**, **replicability**, **simplicity**, and others.
