Returns an {@link AggregatedHttpResponse} generated from the given {@link HttpStatus}, {@code message}
and {@link Throwable}. When {@code null} is returned, the next {@link ServerErrorHandler}
in the invocation chain will be used as a fallback (See {@link #orElse(ServerErrorHandler)}
for more information).

<p>Note: This method can be invoked by Armeria in combination with the other methods in
{@link ServerErrorHandler} or even independently, and thus should not be used for counting
{@link HttpStatusException}s or collecting stats. Use
{@link #onServiceException(ServiceRequestContext, Throwable)} and
{@link #onProtocolViolation(ServiceConfig, RequestHeaders, HttpStatus, String, Throwable)} instead.

@param ctx the {@link ServiceRequestContext} of the request being handled, or {@code null} in case of
           severe protocol violation.
@param config the {@link ServiceConfig} that provides the configuration properties.
@param headers the received {@link RequestHeaders}, or {@code null} in case of severe protocol violation.
@param status the desired {@link HttpStatus} of the error response.
@param description an optional human-readable description of the error.
@param cause an optional exception that may contain additional information about the error, such as
             {@link ContentTooLargeException}.

@return an {@link AggregatedHttpResponse}, or {@code null} to let the next handler specified with
        {@link #orElse(ServerErrorHandler)} handle the event.
