eloquent-json-relations: Strange bug when calling relationship in accessor

Strange but was trying to call a relationship in an accessor like so

public function getOptionsAttribute($value) {
        
    //wanted to loop through the actual relation because it carries the additional data needed
    // just a test...to see what is returned
    error_log(print_r( $this->roles->get()->toArray(), true ));

    return json_decode($value, true);
}

then if I call the relationship or try to retrieve the options attribute like so… (I used tinker to test)

\App\User::find(7)->roles or \App\User::find(7)->options

…I get the following

PHP Notice: Undefined property: App/User::$roles[]->role_id in /path_to_project/vendor/staudenmeir/eloquent-json-relations/src/Relations/BelongsToJson.php on line 97

line 97 refers to this line below in the addConstraints() method of BelongsToJson.php $this->query->whereIn($table.'.'.$this->ownerKey, (array) $this->child->{$this->foreignKey});

Calling other relationships this way, within the accessor, seem to work except BelongsToJson
