        $this->setDescription("imports-produts");
        $this->setDefinition([
            new InputArgument(self::NAME_ARGUMENT, InputArgument::OPTIONAL, "Name"),
            new InputOption(self::NAME_OPTION, "-a", InputOption::VALUE_NONE, "Option functionality")

use Magento\Framework\App\State;

protected $_appState;


public function __construct(
    ...
    State $appState
    ....
) {
    ....
    $this->_appState = $appState;
    ....
}

Now in your code set area which want (i.e frontend or adminhtml) for example,

  $this->_appState->setAreaCode('adminhtml');
