<?php
    public function process(ServerRequestInterface $request, RequestHandlerInterface $handler): ResponseInterface
    {
        $response = $handler->handle($request);
        $stream = $response->getBody();
        if (!$stream instanceof DataStream) {
            return $response;
        }
        $converterClass = $stream->getConverter();
        if ($converterClass === null) {
            # todo: get most relevant format from header
            $converterClass = PrintRConverter::class;
        }
        /** @var Converter $converter */
        $converter = $this->container->get($converterClass);
        $stream->render($converter);

        return $converter->setHeaders($response);

The expression return $converter->setHeaders($response) returns the type Psr\Http\Message\MessageInterface which includes types incompatible with the type-hinted return Psr\Http\Message\ResponseInterface.
