eth_newFilter does not exist/is not available on bsc mainnet

[leowkong]

The README shows that the devel branch has already support eth_newFilter , but when I test the rpc of eth_newFilter on a archive node of bsc mainnet , the rpc has show it not support. I have already update the code into newest devel branch

[root@tf]# curl --location --request POST 'localhost:9548/' --header 'Content-Type: application/json' --data-raw '{"jsonrpc":"2.0","method":"eth_newFilter","params":[{"topics":["0x12341234"]}],"id":73}' {"jsonrpc":"2.0","id":73,"error":{"code":-32601,"message":"the method eth_newFilter does not exist/is not available"}}

@leowkong maybe we by mistake limit it to websockets only, can you try with the websockets enabled and using ws connection instead?

@leowkong maybe we by mistake limit it to websockets only, can you try with the websockets enabled and using ws connection instead?

python: 3.9.7 web3: 5.30.0 erigon: the new update devel branch rpcdaemon cli: rpcdaemon --datadir /node/erigon --http.api=eth,erigon,web3,net,debug,trace,txpool --http.addr=192.168.XX.XX --ws

` from web3 import Web3, HTTPProvider, WebsocketProvider #w3 = Web3(WebsocketProvider("wss://mainnet.infura.io/ws/v3/xxxxxxxxxxxxxxx")) <----------it works w3 = Web3(WebsocketProvider("ws://xxxxxxx:8545"))

usdt_address = "0xdac17f958d2ee523a2206206994597c13d831ec7" #USDT event_signature_hash = w3.keccak(text="Transfer(address,address,uint256)").hex() event_filter = w3.eth.filter({
"address": w3.toChecksumAddress(usdt_address), "topics": [event_signature_hash] }) `

still return error info {'code': -32601, 'message': 'the method eth_newFilter does not exist/is not available'}

@mandrigin seems not support on ws

[root@tf_nodereal_prod_archive_nvme2_ec2 rpctest]# wscat -c ws://10.****:9548 Connected (press CTRL+C to quit)

{"jsonrpc":"2.0","method":"eth_newFilter","params":[{"fromBlock": "0xe20360", "toBlock": "0xe20411", "address": "0x6b175474e89094c44da98b954eedeac495271d0f","topics": []}],"id":1}' < {"jsonrpc":"2.0","id":1,"error":{"code":-32601,"message":"the method eth_newFilter does not exist/is not available"}}

I added a log to see what http APIs we have enabled, but I am looking into this too

[MysticRyuujin]

It looks like eth_newFilter works over HTTP but not WS. WS says it doesn't exist but HTTP works fine.

You have to have the access rules to make it available over HTTP though.

I have been trying to use it on goerli through HTTP and I get the same error. I have been looking at the reason why it might not be getting exposed.

[MysticRyuujin]

Do you have --rpc.accessList defined?

See #4541

[leowkong]

@MysticRyuujin have not set --rpc.accessList flags

Got same error on ETH mainnet with ws connection.

[leowkong]

@MysticRyuujin if we set the eth_newFilter to config file which can be work by --rpc.accessList, we also need to specify ALL individual methods in the rules.json file. it is seems not friendly as we need support all the rpc methods.

[MysticRyuujin]

I completely agree. I'm not a maintainer and it was not my decision to require the ACL. However, the complete list of supported methods is in the rpcdaemon README. Copy, paste.
