org.mozilla.javascript.EcmaError: ReferenceError for function

Consider this code:

var lib = {
	foo: function(node) {
		logger.debug("" + node.name);
	}
};

var sql = "select 'workspace://SpacesStore/af9f95ac-dfdd-4787-b044-22e2026c4e74'"; // some existing NodeRef

var result = database.query("dataSource", sql);

var nodesToMigrate = [];

for each (var row in result) {
    var node = search.findNode(row[0]);
    if (!node || !node.exists()) {
        continue;
    }
    nodesToMigrate.push(node);
}

var process = function process(node) {
    logger.info("processing " + node.typeShort + " " + node.nodeRef);

    // calling function from `lib` fails!
    lib.foo(node);
};

var beforeProcessFunction = function beforeProcess() {
};

var afterProcessFunction = function afterProcess() {
};

batch.runForNodes('Process-', 2, 10, nodesToMigrate, process, true, beforeProcessFunction, afterProcessFunction);

Observed Behaviour

This will throw

Expected Behaviour

The lib.foo function is executed.

I do not know if we can fix that?! Any ideas?
