Looking at the exception is seems there's something not configured correctly in your Lumen application. It's missing a database connection container binding.

I found the solution. To install successfully at Lumen I need to register the config file in bootstrap/app.php

$app->configure('excel');

and set the db.connection to null in config/excel.php

'transactions' => [
        'handler' => 'null',
    ],
