Ardu-stim error message

Good evening
I tried to use this ready-made code that is specific to (ardu-stim), but a error message arose when verify it before downloading it, ('class SerialUI::SerialUI' has no member named 'setTimeout'; did you mean 'setName)
Can you help me solve it,
note that the code link is https://gitlab.com/librems-suite/ardu-stim

Is there any way of seeing the code without an account?
