Global variable inside function scope not working - async.series

Question

I'm trying to set a global variable for the function in order to use it in all functions inside a scope. Functions are called one after another using async.series :

  exports.update = function(req, res, next){

    var result = {};      // setting global var for the scope

    var function1 = function(callback) {
      MyModel.findOne(conditions)
        .lean()
        .exec(function(err, docs) {
          if (err) {
            return callback(err, null);
          }

          result.docs = docs; // assigning function result to global var

          return callback(null, 'done');
        });
    };

    var function2 = function(callback) {
      var fieldsToSet = {
        // ...
        somefield: result.docs.someproperty // error here result.docs = null
      };

        Mymodel.create(fieldsToSet, function(err, record) {
          // ...
        });
    };
    };

    require('async').series([function1, function2]);
  };

Returns error:

TypeError: Cannot read property 'someproperty' of null

How in this case I get the property? Thank you.

Old answer

Declare result outside of exports.update . Must work in this case.

EDIT : Probably make result equal to an empty object inside the function as well, if that's what you want.

@ASem : if you're still up for it, maybe define result.docs = {}; right under result ?
