    message = "Auth error"
    status_code = status.HTTP_401_UNAUTHORIZED


@app.exception_handler(FancyHTTPException)
async def http_exception_accept_handler(request: Request, exc: FancyHTTPException) -> JSONResponse:
    return JSONResponse(
        status_code=exc.status_code,
        content=[{"code": exc.code, "type": exc.type, "message": exc.message}]
    )


@app.get("/")
