🐛 Bug Report

As of a few weeks ago, I was able to successfully find unspent records and execute private transfers on testnet. However now something seems wrong the AleoApiClient. When trying to find unspent records, I get this error:

Error: Failed to parse blocks 5050 (inclusive) to 5099 (exclusive): Failed to read JSON: Failed to parse string. Parsing Error: VerboseError { errors: [("sr1yvt089c2zf09hhuzrxaty20ymjyz3sz6x2rkje9c7a86kn9tevxsm4gpd5", Nom(OneOf)), ("sr1yvt089c2zf09hhuzrxaty20ymjyz3sz6x2rkje9c7a86kn9tevxsm4gpd5", Nom(Many1))] } at line 1034 column 3

That error comes from AleoApiClient.get_blocks. When I drill down the call stack, I can get the url it's hitting, and when I hit that in postman, it's valid json. It also fails for a similar reason when just getting a single block with get_block. According to the line/col numbers, it seems to fail at the last character of the response, despite being valid json.

I notice there's a reference to nom in the errors, which is a dep of some of the snarkvm packages.

aleo_rust hasn't been updated in months, and is using the old, version 14 of snarkvm, while the most recent version is 16, perhaps that's related? Although I don't know why my code was working before.

Steps to Reproduce

Code snippet to reproduce

use aleo_rust::AleoAPIClient;
use snarkvm_console::network::Testnet3;

let api_client = AleoAPIClient::<Testnet3>::new("https://apiv2.aleo.network", "testnet3").unwrap()
let block = api_client.get_block(5538).unwrap();

Stack trace & error message

Error: Failed to parse blocks 5050 (inclusive) to 5099 (exclusive): Failed to read JSON: Failed to parse string. Parsing Error: VerboseError { errors: [("sr1yvt089c2zf09hhuzrxaty20ymjyz3sz6x2rkje9c7a86kn9tevxsm4gpd5", Nom(OneOf)), ("sr1yvt089c2zf09hhuzrxaty20ymjyz3sz6x2rkje9c7a86kn9tevxsm4gpd5", Nom(Many1))] } at line 1034 column 3

Expected Behavior

It was supposed to get the block instead of erroring out.
