What line(s) fail(s) exactly? Or perhaps post the contents of the config.json file?

It is showing this error

concrete\vendor\doctrine\orm\lib\Doctrine\ORM\ORMException.php

* @param string $className
* @param string $fieldName
*
* @return ORMException
*/
public static function missingIdentifierField($className, $fieldName)
{
return new self("The identifier $fieldName is missing for a query of " . $className);
}

That's where the error is thrown, but not where it actually comes from. It's somewhat deeper. Can you post more maybe?

I corrected the issue. it was because controller file of a newly created block was missing.
