Electrum-server with testnet error

[crazylol]

Hi all!

I'm trying to start electrum-server with testnet, but after hours of creating database it fails with error in logs.

This is my steps:
1) I have a full-node of bitcoind, which run with testnet:

Code:

$ bitcoin-cli getinfo
{
  "version": 130200,
  "protocolversion": 70015,
  "blocks": 1092963,
  "timeoffset": 0,
  "connections": 8,
  "proxy": "",
  "difficulty": 2528103.236677098,
  "testnet": true,
  "paytxfee": 0.00000000,
  "relayfee": 0.00001000,
  "errors": "Warning: unknown new rules activated (versionbit 28)"
}

This node is fully synchronise with testnet.

2) I changed in run_electrum_server.py line #116 to

Code:

config.set('network', 'type', 'bitcoin_test')

3) I started electrum-server and all was fine, but after several hours of creating database in logs appears this messages:

Code:

There are many messages like "ERROR: cannot parse" with different IDs.

Can you explain this messages? Please, help me to run electrum-server with testnet.

I know this isn't the question you asked, but i'd suggest to forget electrum-server and switch to electrumx:
https://github.com/kyuupichan/electrumx/blob/master/docs/HOWTO.rst

They should work perfectly on testnet, since it's even in their environment:
https://github.com/kyuupichan/electrumx/blob/master/docs/ENVIRONMENT.rst

NET

Must be a NET from one of the Coin classes in lib/coins.py. Defaults to mainnet.

Note Bitcoin Core >= 0.13.1 requires a special NET for testnet: testnet-segwit.

Thank you!
