Accessing bytes.buffer from createCursor() results in undefined error within react-native

Check existing issues

• I checked there isn't already an issue for the bug I encountered.

Viem Version

2.37.12

Current Behavior

When prepareUserOperation is called within react-native project an error is thrown stating

[TypeError: Cannot read property 'buffer' if undefined]

Since project has global buffer polyfill and stack trace ends at createCursor function I'm thinking there is an issue with accessing bytes.buffer (probably there will be follow up issues with accessing anything on bytes there as well).

Expected Behavior

Should not throw in react-native or documentation should mention necessary polyfills.

Steps To Reproduce

Existing polyfills of the project for refference

import 'react-native-get-random-values'

import { Buffer } from 'buffer'

global.Buffer = Buffer

Call prepare user op on bunlder

const baseSepoliaClient = createPublicClient({
  chain: baseSepolia,
  transport: http('...'),
})

const baseSepoliaBundler = createBundlerClient({
  client: baseSepoliaClient,
  transport: http('...'),
})

const userOp = await baseSepoliaBundler.prepareUserOperation({
    account,
    calls: [{
        to: '0xd...',
        value: parseEther('0.0001'),
    }],
 })
