The exception handling logic checks ex.getCause() for HttpClientErrorException.NotFound, but if chromaApi.getCollection() directly throws HttpClientErrorException.NotFound (not wrapped), this check will fail and re-throw the exception incorrectly. Consider also checking if ex itself is an instance of HttpClientErrorException.NotFound before checking the cause: if (!(ex instanceof HttpClientErrorException.NotFound || ex.getCause() instanceof HttpClientErrorException.NotFound))
