Summary

Seemingly starting in v24, on multiple nodes, querying an unopened block with accounts_balances returns:
"error": "Account not found"
The same block queried with account_balance returns as expected

Node version

v24RC2

Build details

N/A

OS and version

Windows, Linux

Steps to reproduce the behavior

1. Send a block to a new, unopened address
2. Call accounts_balances on the address

Expected behavior

https://docs.nano.org/commands/rpc-protocol/#accounts_balances

Actual behavior

{
    "balances": {
        "nano_37rc7hmpbhaxiiuycptn9shusdiefzwbmh6qj4mcfzex98idmqd4rtm9pkum": {
            "error": "Account not found"
        }
    }
}

Possible solution

This appears to be a bug related to changes introduced in v24, as the issue doesn't appear to be present in v23.3 nodes
