Error EV3 Motors:

Recently, I’ve been trying to create a controller app for LEGO EV3. I can connect to the EV3 successfully, but I’m unable to make the motors rotate. I would like to know if anyone who has already developed a similar app could help me, as I’m encountering some errors that are likely related to the motors. I have tried everything to make these motors rotate.

Here is the programming, I just need the motor movement. :brazil:
