The method eth_subscribe_newHeads does not exist/is not available #644

Closed feiyan-cs closed 5 years ago

feiyan-cs commented 6 years ago

Hello, I am scratching my head here, I am trying to integrate ETC with our exchange but I can't subscribe to newHeads or newPendingTransactions events. newHeads give me this error and newPendingTransactions mean while no error but no event is being triggered either.

I am using web3.js from https://github.com/ethereum/web3.js and my ETC geth start cmd is geth --rpcapi "all" --ws --wsaddr "0.0.0.0" --wsport "8546" --wsorigins "*" --chain=morden --fast --port "30304"

Could you specify which error newHeads event is throwing

@feiyan-cs I'm wondering where you found the reference for eth_subscribe_newHeads, or where you've used it before?

Noting that it's not cited in the following documents:

And the interface seems unavailable in ETH

, though the code does look available: https://github.com/ethereum/go-ethereum/blob/master/eth/filters/filter_system.go#L287

I am using the same code which is successful for ETH, but it doesn't work for ETC.

Am I missing anything? Not available on ETC?

feiyan-cs commented 6 years ago

Basically my code is using standard web3.js from https://github.com/ethereum/web3.js/

web3.eth.subscribe('newBlockHeaders', function(){/...../})

I am getting the same error when I call web3's web3.eth.sendSignedTransaction

aarthiKannanEY commented 5 years ago

Hi any resolution for this error? I am observing the same using dockerized geth with web3.

gabmontes commented 5 years ago

@whilei this is actually the response to a standard newHeads subscription attempt by web3 ({"id": 1, "method": "eth_subscribe", "params": ["newHeads"]}) which follows what is documented here too:

https://github.com/ethereumproject/go-ethereum/wiki/RPC-PUB-SUB#newheads

Is this actually implemented, despite it is documented in the wiki?
