[swtrse]

System information

Erigon version: 2021.09.3-alpha

Expected behavior

Rpc daemon serves request or at least there should be a way to configure the maximum accepted frame size.

Actual behavior

Steps to reproduce the behavior

1. Run rpc daemon and erigon configured for ropsten
2. Use bitcore-node configured to use erigon and rpc daemon as client.
