APP_SERVER env var not found when deploying with EasyDeploy - php

Question

I have this error when the deploy script tries to install the assets:
(Setup PHP 7.2, Symfony 4.4)
[Symfony\Component\Process\Exception\ProcessFailedException]
The command "ssh -A root#vps.net -p 21 '(export APP_ENV=prod; cd /var/www-deploy/site.com/releases/20191129224025
&& php /var/www-deploy/site.com/releases/20191129224025/bin/console assets:install /var/www-deploy/site.com/releases/20191129224025/public --symlink --no-debug --env=prod)'" failed.
Exit Code: 1(General error)
Working directory: /Users/coil/Sites/site.com
Output:

Error Output:

In EnvVarProcessor.php line 162:
Environment variable not found: "APP_SERVER".
I have put the .env file in the shared files, so it's copied when the release directory is created, this file is in the directory.
public function configure(): DefaultConfiguration
{
return $this->getConfigBuilder()
// ...
->sharedFilesAndDirs(['.env'])
// ...
}
I also tried to put the env vars in the .bashrc file of the user who deploys:
printenv | grep -i app
APP_DEBUG=0
APP_SECRET=whatever
APP_ENV=prod
APP_SERVER=prod
So, I don't understand, why the environment variables are still not found. And why they are not taken from the .env file.
If I interrupt the deployment and if I manually run the same command on the server it works well. Thanks.
[Edit 2019-11-30] I think I understand know, when running the command, there is an export of the APP_ENV that is done. And, if the application detects this env variable it will just skip the .env file. So, I need to avoid setting this env var, or I must set all instead of this one only.

[Edit 2021-02-13] I have fixed the bin/console file and removed the "hack". Instead of testing the APP_ENV var I test the APP_SECRET one which is not set by EasyDebug:
if (!isset($_SERVER['APP_SECRET'])) {
(new Dotenv())->load(__DIR__.'/../.env');
}
Old solution:
It now works with the following modififications, in src/Configuration/DefaultConfiguration.php:
} elseif (4 === $symfonyMajorVersion || (3 === $symfonyMajorVersion && 4 >= $symfonyMinorVersion)) {
$this->_symfonyEnvironmentEnvVarName = 'APP_ENV';
I have passed an unkown env var to Symfony:
$this->_symfonyEnvironmentEnvVarName = 'APP_FAKE_ENV';
So the .env file is not ignored any-more. I think there is a missing option to set or not this environment var based on the setup of the application. I'll try to do a PR to the bundle.
So, as the bundle is not modified yet, I have modified the private property, in order to make the command use my .env files instead of environment variables:
/**
* #see https://stackoverflow.com/q/1762135/633864
*/
private function forceEnvironmentEnvVarName(DefaultConfiguration $configuration): DefaultConfiguration
{
$myClassReflection = new ReflectionClass(get_class($configuration));
$symfonyEnvironmentEnvVarName = $myClassReflection->getProperty('_symfonyEnvironmentEnvVarName');
$symfonyEnvironmentEnvVarName->setAccessible(true);
$symfonyEnvironmentEnvVarName->setValue($configuration, 'FAKE_APP_ENV');
$symfonyEnvironmentEnvVarName->setAccessible(false);
return $configuration;
}
