If you want to try expressive I suggest to use the skeleton installer. It gives you options on what to install. One of the options is the whoops error handler which gives a lot of detailed info about exceptions.
The official docs are here with a lot of info: https://docs.zendframework.com/zend-expressive/

Update: Add ErrorHandler logger example
As a base for your ErrorHandler you can use Zend\Stratigility\Middleware\ErrorHandler. You can attach a listener to that ErrorHandler and use it for logging. Alternatively you can copy that class and modify it to your needs.
Next step is creating a ErrorHandlerFactory for it:
<?php
// src/Factory/ErrorHandler/ErrorHandlerFactory.php
namespace App\Factory\ErrorHandler;
use Interop\Container\ContainerInterface;
use Psr\Http\Message\RequestInterface;
use Psr\Http\Message\ResponseInterface;
use Psr\Log\LoggerInterface;
use Throwable;
use Zend\Diactoros\Response;
use Zend\Expressive\Middleware\ErrorResponseGenerator;
use Zend\Stratigility\Middleware\ErrorHandler;
class ErrorHandlerFactory
{
public function __invoke(ContainerInterface $container)
{
$generator = $container->has(ErrorResponseGenerator::class)
? $container->get(ErrorResponseGenerator::class)
: null;
$errorHandler = new ErrorHandler(new Response(), $generator);
if ($container->has(LoggerInterface::class)) {
$logger = $container->get(LoggerInterface::class);
$errorHandler->attachListener(function (
Throwable $throwable,
RequestInterface $request,
ResponseInterface $response
) use ($logger) {
$logger->error('"{method} {uri}": {message} in {file}:{line}', [
'date' => date('Y-m-d H:i:s'),
'method' => $request->getMethod(),
'uri' => (string) $request->getUri(),
'message' => $throwable->getMessage(),
'file' => $throwable->getFile(),
'line' => $throwable->getLine(),
]);
});
}
return $errorHandler;
}
}
After that you need to register the ErrorHandler. You do this by adding it to config/autoload/middleware-pipeline.global.php and specifically in the middleware => always section. This way it will always run. If you register it as first, it will run before anything else.
<?php
// in config/autoload/middleware-pipeline.global.php
use Acme\Container\ErrorHandlerFactory;
use Zend\Stratigility\Middleware\ErrorHandler;
return [
'dependencies' => [
/* ... */
'factories' => [
ErrorHandler::class => ErrorHandlerFactory::class,
/* ... */
],
/* ... */
],
'middleware_pipeline' => [
'always' => [
'middleware' => [
ErrorHandler::class,
/* ... */
],
'priority' => 10000,
],
/* ... */
],
];
