Motor Hall Magnetic Encoder got Error 3 (wiring)

[sxaris87]

Hello, at the beginning i use Rotary Encoder for 1-2 months and then after i was damaged it i replaced it with Sonar. I change the motor too with this With Sonar i was not happy because everything under the desk must be clear (even my feet was problem for sonar). After that i saw Hall Magnetic Encoder i bought it form aliexpress Link and i print the case and the bought bearing too Link Now when i connect Motor Hall Magnetic Encoder got Error 3 (wiring)

What i m doing wrong? motor power terminals from sensor hall not connecting anywhere, right?

In sort i disconnect Sonar and i connect Sensor Hall and i got wiring error i connect blue cable to 5V green to GND and yellow/white i try it both A/B or B/A and the results the same error 3 (wiring). have to change the code or something?
