namespace Staudenmeir\EloquentEagerLimitXLaravelAdjacencyList\Eloquent\Relations;

use Illuminate\Database\Query\Expression;
use RuntimeException;
use Staudenmeir\EloquentEagerLimitXLaravelAdjacencyList\Eloquent\Relations\Traits\HasEagerLimit;

class Descendants extends Base
{
    use HasEagerLimit;

The trait Staudenmeir\EloquentEagerLimitXLaravelAdjacencyList\Eloquent\Relations\Traits\HasEagerLimit requires the property $exists which is not provided by Staudenmeir\EloquentEagerLimitXLaravelAdjacencyList\Eloquent\Relations\Descendants.

    /**
     * Set the "limit" value of the query.
     *
     * @param int $value
     * @return $this
     */
    public function limit($value)
    {
        if ($this->parent->exists) {
            $this->query->limit($value);
        } else {
            if ($this->andSelf) {
                $grammar = $this->getEagerLimitGrammar();

	            $sql = $grammar->compileFirstPathSegment(
		            $this->related->qualifyColumn(
			            $this->related->getPathName()

It seems like $this->related->getPathName() can also be of type Illuminate\Database\Eloquent\Builder; however, parameter $column of Illuminate\Database\Eloquent\Model::qualifyColumn() does only seem to accept string, maybe add an additional type check?

		            )
	            );

	            $column = new Expression($sql);

                // TODO
                //		    if ($grammar instanceof MySqlGrammar && $grammar->useLegacyGroupLimit($this->query->getQuery())) {
                //			    $column = 'laravel_through_key';
                //		    }

                $this->query->groupLimit($value, $column);

	            $this->query->getQuery()->addBinding(
		            array_fill(
			            0,
			            substr_count($sql, '?'),
			            $this->related->getPathSeparator()
		            ),
		            'groupBy'
	            );
            } else {
                throw new RuntimeException('Eager loading limits are not supported on Descendants relationships.');
            }
        }

        return $this;
    }
