Cannot run echo server

[elaine030490]

I'm trying to run the echo service example mentioned here - https://microraiden.readthedocs.io/en/latest/tutorials/try-echo-service.html
I've completed the microraiden installation and set up geth as per the instructions.

When I run the command to start the microraiden receiver-
python microraiden/examples/echo_server.py --private-key microraiden/examples/pk_tut.txt,
I get the following error -

  File "/home/harshreddy/env/lib/python3.6/site-packages/web3/contract.py", line 794, in call_contract_function
    output_data = decode_abi(output_types, return_data)

    len(data),

The above exception was the direct cause of the following exception:

I'm running on Ubuntu 18.04.1 LTS

I tried using Geth as well. It takes a long time to sync. I recommend downloading parity instead and using that. It still took me about 3 hours to sync fully. You can download parity from here: https://wiki.parity.io/Setup . After it syncs, you shouldn't be getting that error.

I had the same problem and @msaxena18 is right. Use Parity and type in the command console "parity --light --cache-size 1024 —chain ropsten --rpcport=8545". This will be the fastest way to sync with ethereum.

Now I have a new problem: I get ValueError: {'code': -32041, 'message': 'Requested data size exceeds limit of 1000 blocks.'}
and
gevent.hub.LoopExit: ('This operation would block forever', <Hub at 0x10ccc5930 select default pending=0 ref=0>)

What could possibly be the solution?
