Is this a bug of the new input system?

Hello everyone,

I’m using the new Input system with code.
I checked the “Generate C# Class” checkbox, and have a code like this (ignored some irrelevant code):

public class PlayerController : MonoBehaviour 
{
    private InputSystemSettings _inputControl;
    private int jumpCounter;
    private Rigidbody2D _rb;

    private void Awake() 
    {
        _inputControl = new InputSystemSettings();
        _inputControl.Player.Jump.performed += JumpPerformed;
        jumpCounter = 0;
    }

    private void Start()
    {
        _rb = GetComponent<Rigidbody2D>();
    }

    private void OnEnable() { _inpputControl.Enable();}
    private void OnDisable() { _inputControl.Disable();}

    private void JumpPerformed(InputAction.CallbackContext context) 
    {
        _rb.velocity = new Vector2(_rb.velocity.x, jumpForce);
        jumpCounter += 1;
        Debug.Log(jumpCounter);
    }
}

so I expect that when I press the jump button (space bar), the console will output 1, and then if I press the jump button again, it will output 2.

However, when I press the jump button, the console outputs 1, and then when I press the jump button again, the console outputs 1 again. if I continue to press the jump button, the console outputs 2, 3, 4, 5…
That means if I press the button 5 times, the output is 1, 1, 2, 3, 4

so is this a new Input system bug? or did I use it in the wrong way?

Any help is appreciated.

Ok, I find out the reason.
it’s I reset the counter value if the player isOnGround equals to true. When I click the jump button, it does not immediately leave the ground, so the counter was set to 0 in this frame.
left this message, in case anybody else has a similar issue.

And I fixed the issue by:

yield return new WaitUntil(() => !_isOnGround);
yield return new WaitUntil(() => _isOnGround);
jumpCounter = 0;
