Problem with multiple database connections

[TataMata]

I have a strange problem if I add config/database.php file to my Lumen installation. Even if I don't use any database connection my service returns an invalid image. I have route:

$router->get('photo', function () use ($router) {
  // create a new empty image resource
  Image::configure(array('driver' => 'imagick'));
  $img = Image::canvas(200, 200, '#ff0000');
  return $img->response('png');
});

in my basic lumen installation and everything works as expected. When I try to add config/database.php file to tailor my database connections (I need to connect to 2 databases at once), even if it is an empty file or copy of vendor/laravel/lumen-framework/config/database.php my route return an invalid base64 encoded image and I can't display it anymore.

It is easy reproducable. Just create new lumen project, require intervention/image and register ImageServiceProvider in the bootstrap/app.php and add route.

I'm using php 7.4 with Apache on Arch Linux (updated). My composer.json:

    "name": "laravel/lumen",
    "description": "The Laravel Lumen Framework.",
    "keywords": ["framework", "laravel", "lumen"],

    },

    },

        "classmap": [
            "tests/"
        ]
    },

    "prefer-stable": true,
    "scripts": {
        "post-root-package-install": [
            "@php -r \"file_exists('.env') || copy('.env.example', '.env');\""
        ]
    }
}

[mfn]

returns an invalid image.

Any errors? Exceptions? Anything in the logfile?

[TataMata]

Nothing at all. I'm, using Firefox's extension RESTClient to test my services and, without database.php file it displays the image as it should, but just with the

<?php
?>

code in the config/database.php file, response changes from: data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAMgAAADIAQMAAACXljzdAAAABGdBTUEAALGPC/xhBQAAACBjSFJNAAB6JgAAgIQAAPoAAACA6AAAdTAAAOpgAAA6mAAAF3CculE8AAAABlBMVEX/AAD///9BHTQRAAAAAWJLR0QB/wIt3gAAABxJREFUWMPtwYEAAAAAw6D5U1/hAFUBAAAAAHwGFFAAAQCfIxUAAAAASUVORK5CYII= to: data:image/png;base64,DQqJUE5HDQoaCgAAAA1JSERSAAAAyAAAAMgBAwAAAJeWPN0AAAAEZ0FNQQAAsY8L/GEFAAAAIGNIUk0AAHomAACAhAAA+gAAAIDoAAB1MAAA6mAAADqYAAAXcJy6UTwAAAAGUExURf8AAP///0EdNBEAAAABYktHRAH/Ai3eAAAAHElEQVRYw+3BgQAAAADDoPlTX+EAVQEAAAAAfAYUUAABAJ8jFQAAAABJRU5ErkJggg== Very strange.

Here is my bootstrap/app.php file content just in case:

});

return $app;

I'm sorry, I just accidentally closed it.

I have just discovered that if I remove first blank line from the config/database.php file everything works fine. I have no idea why this is happening and I find it very odd. I have lost few days trying to figure it out. I'm closing this thread.
