Error when performing a query

[nomadster]

I'm doing this

this.get = function*(username){
        if(!username){
            throw new Error('Missing parameter');
        }
        var query = [
            'MATCH (u:User {username: {usr}})-[:has_bookmark]->(b:Bookmark)',
            'RETURN b.blob'
        ];

        var params = {
            usr: username
        };

        return yield GraphDBService.query(query,params);
    };

with GraphDBService.query() being kind of a wrapper that call yours query() like this

this.query = function(query, params, transformResultFunction){

        transformResultFunction = transformResultFunction || identityFunction;

        return function(callback){
            db.query(query, params, function(err, res){
                if(err){
                    callback(err);
                } else {
                    res = transformResultFunction(res);
                    callback(undefined,res);
                }
            });
        };
    };

transformResultFunction being an optional argument that does what it says :)

When executing the query i get the following error

Error

I'm wondering if I'm doing something wrong or I've just spotted a bug. Let me know if I have to send additional informations. :)

I forgot a .join('\n'); Sorry. :(

Glad you figured it out!

I'm surprised the error message is empty in this case though. I'll try to take a look at it later.
