under `server_id` label.
Removal of `serv_node_version` is scheduled for Sep-Oct 2023 (~0.105.0 release).
## RPC error codes returned by old versions and C#-nodes
NeoGo retains certain deprecated error codes: `neorpc.ErrCompatGeneric`,
`neorpc.ErrCompatNoOpenedWallet`. They returned by nodes not compliant with the
neo-project/proposals#156 (NeoGo pre-0.102.0 and all known C# versions).
Removal of the deprecated RPC error codes is planned once all nodes adopt the new error standard.

NeoGo currently uses a different set of error codes in comparison to C# implementation, see
[proposal](https://github.com/neo-project/proposals/pull/156).

##### `getnep11transfers` and `getnep17transfers`
`transfernotifyindex` is not tracked by NeoGo, thus this field is always zero.
##### `traverseiterator` and `terminatesession`
NeoGo returns an error when it is unable to find a session or iterator, unlike
the error-free C# response that provides a default result.
##### `verifyProof`
NeoGo can generate an error in response to an invalid proof, unlike
the error-free C# implementation.

Methods listed below are not going to be supported for various reasons
