Nightwatch: .elementIdElements() is broken

[devastadus]

Using nightwatch 0.9.16
node v8.4.0
Selenium 3.4.0
MacOs 10.12.6

I have a function that goes through a table and logs the first cell of every row in the table.

getTableRowByFirstRowName: function(schoolName){
        let api = this.api;
        api.elements('xpath','//tbody/tr',function (rows) {
            rows.value.forEach(function(row){
                api.elementIdElements(row.ELEMENT,function (cells) {
                    api.elementIdText(cells[0].ELEMENT,function (firstCellName) {
                        console.log(firstCellName.value);                        
                    });
                });
            });
       });
    },

my program errors out on the .elementIdElements and returns this error

Error while running elementIdElements command: using.toLocaleLowerCase is not a function

When i drill into the .elementIdElements using = using.toLocaleLowerCase(); is the 3rd line of the function that i think is the problem.
