I have been following the make your own game in 3D tutorial in getting started section of godot's docs, I did everything as it's written in the website, however, the collisions are not working

the section of the tutorial https://docs.godotengine.org/en/stable/getting_started/first_3d_game/06.jump_and_squash.html

I tried to print the collider whenever there is a collision, it does print the ground, however, whenever a collision happens with enemies, nothing is printed, here is the code

player.gd

extends CharacterBody3D
# How fast the player moves in meters per second.
@export var speed = 14
# The downward acceleration when in the air, in meters per second squared.
@export var fall_acceleration = 75
# Vertical impulse applied to the character upon jumping in meters per second.
@export var jump_impulse = 20

# Vertical impulse applied to the character upon bouncing over a mob in
# meters per second.
@export var bounce_impulse = 16

var target_velocity = Vector3.ZERO

func _physics_process(delta):
        #...
    # Going through all the colliders
    for index in range(get_slide_collision_count()):
        
        # We get one of the collisions with the player
        var collision = get_slide_collision(index)

        # If the collision is with ground
        if collision.get_collider() == null:
            continue
        # If the collider is with a mob
        if collision.get_collider().is_in_group("mob"):
            print(collision.get_collider())
            var mob = collision.get_collider()
            mob.squash()
            break
    move_and_slide()

mob.gd

extends CharacterBody3D

# Minimum speed of the mob in meters per second.
@export var min_speed = 10
# Maximum speed of the mob in meters per second.
@export var max_speed = 18
signal squashed

func squash():
    squashed.emit()
    queue_free()

collision layers and masks are correctly set, and I made a group as well for mobs, like shown in the screenshot

Godot Engine documentation
Jumping and squashing monsters

In this part, we'll add the ability to jump and squash the monsters. In the next lesson, we'll make the player die when a monster hits them on the ground. First, we have to change a few settings re...

Outside the conditional it does print the ground, I changed the print to inside the conditional that checks for the group , it's always false

You're absolutely sure the collision layers and masks are set up correctly?
