TypeError: (0, paddedBits_1.bitsToPaddedBuffer)(bits).copy is not a function (it is undefined

[divyangkhatri]

Hello,
Version Details
react-native: 0.75.1
"@ton/core": "^0.56.3",
"@ton/crypto": "^3.3.0",
"@ton/ton": "^14.0.0",

When i just import the @ton/ton package, I am facing this error "TypeError: (0, paddedBits_1.bitsToPaddedBuffer)(bits).copy is not a function (it is undefined" after updating the react-native version. 0.72.7 to 0.75.1.
Previously it was working fine in older version of RN.
On the below line there is the crash

ton-core/src/boc/cell/descriptor.ts

Line 35 in b5aa938

bitsToPaddedBuffer(bits).copy(repr, reprCursor);

I also attach the screenshot of the error

There are several ways to fix this.
The first one is the fastest but also the dirtiest:

Uint8Array.prototype.copy = Buffer.prototype.copy;

However, the issue is not with the copy method but with the subarray method (feross/buffer#329).

The problem description provides ways to patch this.
You can patch the subarray method separately.

But I would recommend using the following library, which resolves all issues related to typed arrays: https://www.npmjs.com/package/@exodus/patch-broken-hermes-typed-arrays.
