Method not found when calling chain_getRuntimeVersion

[xlc]

chain_getRuntimeVersion no longer exists, possibly related to #1679

curl -H 'Content-Type: application/json' -d '{ "jsonrpc": "2.0", "method":"chain_getRuntimeVersion", "params":[], "id": 1 }' http://localhost:9933/
{"jsonrpc":"2.0","error":{"code":-32601,"message":"Method not found"},"id":1}

@jacogr Maybe should fix it on polkadot.js side to use state_getRuntimeVersion and remove chain_getRuntimeVersion? but state.getRuntimeVersion is missing anyway

Ok, this is problematic. Since the APIs needs to support both old and new chains and this is not detectable without a call. (If moved and not just deprecated with new version)

If this was a move of endpoints, will look at it a bit later to try and find a solution for this ASAP since we seem to have broken apps out there.

Hmm, the alias still exists. So the function should also still exist. Sounds like a bug.
@ascjones any ideas why this is missing?

Probably a bug in jsonrpc-derive. Investigating.

@ascjones Tested, does the trick for me on latest master, thank you.
