I2C Display - Write Error 33281

I feel like I am really missing something here. I have a 1602 display with an ic2 backpack. I am connecting it to a MDBT42Q Breakout, and using this doc: http://www.espruino.com/HD44780

I have tried different pins. I have also added pull up resistors from vcc (5v) to scl and sda

Here is the error I get. ...
