Partial text sent when using SendKeys in Protractor

Question

Inconsistently, the partial text is being sent when using SendKeys and causes a particular spec to fail. Below is the test that needs to happen for the other tests to past successfully

    it('should select a template report', function() {
        reports.createTemplateBtn.click();
        reports.selectTemplate.click();
        browser.switchTo().activeElement().sendKeys('Guest RSVP Status' + protractor.Key.ENTER);
        browser.sleep(1000);
        reports.startBtn.click();
    });

The test is clicking a field (Select Template) which then shows a drop-down to type in the type of template to be used. The issue is with sending 'Guest RSVP Status'. Inconsistently, only portions of the phrase will be sent and cause the rest to error out. Is there a better way to implement Send Keys and/or should sleeps be added? 1/5 times the full text is sent successfully.

Update: slowType errors out below. Sleep is not a function.

function slowType(elm, keys, delay){
        var action = browser.actions().mouseMove(elm).click();
        for (var i = 0; i < keys.length; i++) {
            action = action.sendKeys(keys[i]).sleep(delay);
        }
        return action.perform();
    }
