Fatal error: Uncaught Zend\HttpHandlerRunner\[...]: Unable to emit response;

Heyho!

First of all : I'm a web developer who's new to Flarum and would like to get known to writing extensions for it.

Now to my problem : I've made a fresh installation, following the guide on https://flarum.org/docs/install.html, on my PC using Homestead.

After I've run composer install I was able to get to the Flarum-Installation page.

I entried all needed informations and was forwarded to the next page, where I'm now stuck with the following error :

( ! ) Fatal error: Uncaught Zend\HttpHandlerRunner\Exception\EmitterException:
Unable to emit response; headers already sent in
/home/vagrant/Projects/flarum/vendor/zendframework/zend-httphandlerrunner/src/Exception/EmitterException.php
on line 18

Screenshot

In case you're asking for "php flarum info", take a look here

Also some short informations about the vagrant machine I'm running :

PHP-Version: 7.3.6.1+ubuntu18.04.1+deb.sury.org+1
MySQL-Version: Version: 5.7.26-0ubuntu0.18.04.1 - (Ubuntu)

http://flarum.test/ is pointing at path/flarum/public.

Thanks in advance & sincerly

Update :

It works now.

How :

I've changed from php-version 7.3 to 7.2.
To change the php-version in homestead, you've just to add php: "7.2" to the mapping.
E.g.:

sites:
    - map: flarum.test
      to: /home/vagrant/Projects/flarum/public
      php: "7.2"

Something still doesn't work :

Localization and Icons aren't working, everytime I open the flarum it looks like this :
alt text
The console says :

[Violation] 'requestAnimationFrame' handler took 87ms
jquery.js:10174 GET http://flarum.test/assets/fonts/fa-solid-900.woff2 net::ERR_ABORTED 404 (Not Found)
jquery.js:6168 GET http://flarum.test/assets/fonts/fa-regular-400.woff2 net::ERR_ABORTED 404 (Not Found)
(index):1 GET http://flarum.test/assets/fonts/fa-regular-400.woff net::ERR_ABORTED 404 (Not Found)

But atleast I can work on it now.
If some of you know how to fix this easily, I'd be glad to hear from you!

Sincerly
