Can't return Metadata for field

[wmoghes]

Hey,

public static function getFieldDef($fieldName)
    {
        $fileManager = new Manager();
        $config = new Config($fileManager);
        // $fieldName passing this value -> investmentPortfolios
        $metadata = new Metadata();
        file_put_contents('/var/www/espocrm/data/logs/x.log', print_r($metadata->get('entityDefs.Account.fields'), true));

    } 

I just adding above code in this location espocrm\custom\Espo\Custom\Hooks\Account but each time I run above code the below error message appears

Hello
in application/Espo/Hooks/Common/Stream.php you have an example with Metadata
why do you create objects, if they are available in this class?

[wmoghes]

I was followed this documentation https://www.espocrm.com/documentatio...ment/metadata/
and I was changed to be like below but still not working and I'm got the same error as I mentioned before

file_put_contents('/var/www/espocrm/data/logs/x.log', 
                            print_r($this->getMetadata()->get('entityDefs.AccountOpening.fields.investmentPortfolios'), true)); 

[wmoghes]

here's the error message

[tanya]

Does your class extend base?

[wmoghes]

yeah I already use extend like below

namespace Espo\Custom\Hooks\AccountOpening;

use Espo\ORM\Entity;
use Espo\Core\Utils\Util;
use Espo\Core\Utils\Metadata;
use Espo\Core\Utils\Config;
use Espo\Core\Utils\File\Manager;

class MissingHandler extends \Espo\Core\Hooks\Base 

[wmoghes]

I tried to change the code to be like this and got the same error -> "PHP Fatal error: Call to a member function get() on null"

public function getFieldDef($fieldName)
    {
        $fileManager = new Manager();
        $config = new Config($fileManager);
        // $metadata = new Metadata($config, $fileManager);// investmentPortfolios
        file_put_contents('/var/www/espocrm/data/logs/x.log', 
                            print_r($this->getMetadata()->get('entityDefs.AccountOpening.fields'), true));
        //$metadata = new Metadata();
        //file_put_contents('/var/www/espocrm/data/logs/x.log', print_r($metadata->get('entityDefs.Account.fields'), true));
        //$field = $metadata->get('entityDefs.AccountOpening.fields.' . $fieldName);
        //$field = $metadata->get('entityDefs.AccountOpening.fields.investmentPortfolios.type');
        //return $field['options'];

    } 

I'm sorry for the inconvenience but I hope if you can help me in this issue because i tried my best
