cannot unmarshal hex string without 0x prefix into Go struct field SendTxAr gs.data of type hexutil.Bytes about cakeshop HOT 22 CLOSED

This also happens with the latest Quorum version (2.0.0) with geth 1.7.3. Would be nice to use cakeshop with the 7 nodes examples with Raft and Istanbul!

from cakeshop.

+1 Have similar issue, any workaround?

from cakeshop.

This seems like it happens due to changes in the geth protocol, requiring certain fields to be hex strings with '0x' prefixes.

I'm slowly tracking down the changes locally (but unsure if will submit PR, as doing a side project). A few I've identified are below - and am now looking for more:

FYI I've given up on Cakeshop and started using https://github.com/blk-io/blk-explorer-free This works with Quorum & Ethereum

from cakeshop.

@horca17 Cakeshop is currently not able to run along 7nodes, tho an upgrade is underway.

from cakeshop.

Which version of cakeshop? What type of node?

from cakeshop.

I used version 0.9.1 as well as 0.10.0. I am trying to run Go ethereum node in attach mode

from cakeshop.

@karthiyogi version 0.9 and the docs currently explain how to attach it to a plain vanilla geth node. Version 0.10 docs haven't been updated yet, but its designed to work with quorum build of geth.

If you have geth, use 0.9 and follow the docs. If somethign occurs, please let me know in detail so I could guide you.

Here are changes (to master) that get the GUI screen up. The only page that works is the Sandbox which will at least allow contract compilation/deploment:

Hi,
thanks for your answer. I've tried to use the blk-explorer, but I didn't manage to get it up and running with the 7nodes example. There seems to be an issue with running vagrant and docker at the same time... Do you have any suggestions how to do that?
Thanks!

from cakeshop.

We don’t use the vagrant 7nodes example as we have our own customised install scripts.
Try contacting the chap who maintains the code on github. His name is Ivaylo. He was quite helpful with an issue I had a while ago.
