Problem with migration to Apache

I have tried to deploy my Grav project to Apache, but it's complicated. I have to test before deploy this Grav's website on shared hosting so I emulated docker-apache-php7.1 enviroment (grav-docker-apache precisely).

When I want to load grav it's throwing following ErrorException:

"array_merge(): Argument #2 is not an array"

in this line:

<code>$defaults = (array)$config->get('system.pages.markdown');
if (isset($this->header()->markdown)) {
$defaults = array_merge($defaults, $this->header()->markdown);
}
</code>

And it's throwing following ErrorException during load admin:

<code>
"Declaration of Grav\Plugin\Babel\BabelSearch::setTokenizer(TeamTNT\TNTSearch\Support\TokenizerInterface $tokenizer) should be compatible with TeamTNT\TNTSearch\ ▶"
</code>

Can someone helps me?

Does your docker image have at least php 7.1.3, as listed in the requirements ?

Yes. PHP 7.1.7 is installed.

It's not apache case definitely. I have deployed this my Grav's project on another Nginx (docker php-fpm 7.3) and Grav throws the same error. Anyone knows why I have this error?

I have enabled php modules on machine:

I have attached screenshot too.

I solve it, but I have another error.

Whoops \ Exception \ ErrorException (E_NOTICE)

Have you have Dockerfile with linux (i.e. alpine, ubuntu), newest php, newest grav and apache/nginx enviroment and all neccessary modules to launch grav?

sure - I'm currently using the official grav docker file from GitHub
even easier to use with this docker-compose.yml file:

version: '2'

services:
grav-php:
image: grav:latest
container_name: grav-php
ports:

• "8080:80"
  restart: always
  volumes:
• ./grav:/var/www/html:cached

(indentation is wrong, I know, probably due to the forum editor...)

Nginix ??? 🤔
