Collection not populated

[KevinBurton]

I have the following code:

        var db = pmongo(mongodbConfig.url, mongodbConfig.options, mongodbConfig.collections);
        for(var i in mongodbConfig.collections) {
            db[mongodbConfig.collections[i]].remove();
        }
        return Promise.all(formDefinitions.map(function (formDefinitionItem) {
            var formDefinition = {};
            for(var formDefinitionProperty in formDefinitionItem) {
                if(formDefinitionItem.hasOwnProperty(formDefinitionProperty)) {
                    if(formDefinitionProperty != 'pages') {
                        formDefinition[formDefinitionProperty] = formDefinitionItem[formDefinitionProperty];
                    }
                }
            }
            return db[mongodbConfig.collections[0]].insert(formDefinition);
        })).then(function(allFormDefinitions) {

When I run this code no exceptions are thrown but the database (looking with the mongo shell) seems empty. Can you see anything obvious that I am doing wrong? The variable 'formDefinitions' is an array that I know is created correctly. The string mongodbConfig.collections is an array of strings and in this case so the string 'formDefinitions'. I have set a breakpoint at each return and the variable 'formDefinition' is correct. I am having a hard time seeing what is wrong that would cause the collection to be empty without error.

Thank you.
