Describe the bug Trying to use the getLedgerEntries on futurenet with the latest sdk.

const wasm_hash = "390c0dc0c56b66db3847d1ab75d8bfda164bda5a7032a049921f5529202ddd95"

const lk = xdr.LedgerKey.contractCode(
    new xdr.LedgerKeyContractCode({
        hash: Buffer.from(wasm_hash, 'hex'),
    })
)

await rpc.getLedgerEntries(lk)

What version are you on? "@stellar/stellar-sdk": "^12.0.0-rc.1",

This works fine on testnet and mainnet.

To help with debugging, this is the XDR for the ledger key:

$ echo '{"contract_code":{"hash":"390c0dc0c56b66db3847d1ab75d8bfda164bda5a7032a049921f5529202ddd95"}}' \
    | stellar-xdr encode --type LedgerKey

Closed by rc.2, thanks for the report!
