bootstrap - get_coinbase_tx_sum returns height or count is too large instead of method not found

[SyntheticBird45]

v0.18.3.1

Using a fresh node that only synced 5973 blocks in database, --no-sync and --bootstrap-daemon-address <ANY NODE URL>

  }
}

Expected Behavior

Node shouldn't tell client that height or count is too large, by solely relying on the database.

I might be missing something but why should it return method not found?

[SyntheticBird45]

because the bootstrap daemon have --restricted-rpc. But I'm realizing it's maybe out of scope for get_coinbase_tx_sum to fetch the response to the bootstrap daemon

[selsta]

The bootstrap-daemon feature was created so that someone can scan a wallet and create a transaction while the local node is still syncing. Endpoints like get_coinbase_tx_sum that require an unrestricted bootstrap node do seem out of scope.

The existing code could be improved for such edge cases but it doesn't seem like high priority.
