Bluetooth commands don't move the servo

hi guys, I'm trying to set up a simple application to be able to control a servomotor through the esp32 via an on and off switch. The servo motor should move from 0 to 180 degrees and back in a loop while the switch is on, and stop when the switch is off. the problem is that the servomotor doesn't move.
The connections with the wires are correct because I tried to move it by commanding it from the PC and it works; at the same time, the bluetooth connection also works, because I tried to print on the serial monitor the bluetooth commands that I send from the phone to the board and it was succesfull. what could be the problem at this point? Thank you!
