MainButton click passes event with evenData undefined

[reloverevolt]

Hello,

I have just noticed that MainButton has broken or something, yesterday it was functioning as expected , but now on each click console just reports:

my component is:
<MainButton text="Buy" onClick={handleMainButtonClick}/>

handler:
`function handleMainButtonClick(): void {
WebApp.onEvent("mainButtonClicked", function(){
const orderBody = {
user: profile?.userId,
items: [{product: selectedProduct["id"], quantity: 1}],
currency: "rub",
promocode: null,
discount_id: discounts ? discounts[0]["id"] : null
};
const requestOptions = {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify(orderBody)
};

        fetch(`${import.meta.env.BASE_URL}ecommerce/api/orders/`, requestOptions)
          .then(response => response.json())
          .then(data => WebApp.sendData(JSON.stringify(data)));
  
      });
}`

I have checked and didn't find any recent updates on the side of telegram or repo
Anyone has an idea of what could be the issue?
