Summary of Bug

RPC requests to nodes when a node is just getting initialized/started trigger the following error:

"rpc error: code = Unknown desc = codespace sdk code 18: invalid request: failed to load state at height 0; version mismatch on immutable IAVL tree; version does not exist. Version has either been pruned, or is for a future block height (latest height: 0)",

The error is being thrown here when creating the context for the query.

It seems that the IAVL tree does not exist at height 0, so the height hasn't been created yet (here is the VersionExists method on the IAVL struct).

Cosmos SDK version previously returned an empty IAVL tree in this scenario. PR that introduced the change is #13355.

This might be related to this other issue.

Version

v0.47.0-alpha2

Steps to Reproduce

• Create some task/job that call a node RPC endpoint
• Start a new node
