### Subject of the issue

Certain blocks make algodv2 client throw this error: `Error: Invalid byte array: (object) null`

One such block is `44295768`

```js
import algosdk from 'algosdk';

const algod = new algosdk.Algodv2('', 'https://mainnet-api.4160.nodely.dev', 443);

try {
const data = await algod.block(44295768).do();
} catch(e) {
