bail[hard]: Invalid params: expected a hex-encoded hash with 0x prefix.

Have a similar issue for the light client with Etherwall 2.3.1 and the latest geth under Windows 10 where I get:

Wait so you get this error only on light client setup or both?

[UGatgithub]

It was only in Thin Clint mode but gone now. Inbetween I updated EthereumWallet/Mist and when I tried to recheck now, the error was gone.

[almindor]

Are you using geth from Mist in Etherwall? I suspect when you updated geth they might've fixed something.

[UGatgithub]

I used Geth 1.8.23 which I downloaded separately. Mist runs with 1.8.21 but independent of the geth version I run now, the error is gone.

I just got the same error.

I was using 2.2.4 and sent some ether. Closed it and downloaded 2.3.1 which gave those errors on startup and when switching to Transactions screen. (I don't use Mist or separate copy of geth.)
Restart gave same error, and block 7478051 (my send) shows up twice in the Transaction page.

[almindor]

Are you getting this consistently? Could you please switch log-level in the Logs tab to debug and restart, get the logs from that and paste them here (or as a file since it might be longer)?

[SnowLeopard71]

Yes, error occurs whenever I start etherwall. Didn't notice until today as I only use it every month or so.
I inserted a newline after the first six lines as these appear exactly 1 minute after the rest.

Thanks, the issue is in Sent: {"id":14,"jsonrpc":"2.0","method":"eth_getTransactionByHash","params":["bc2062aae990a9fddc037d291e840ad449b47eea850a107bf8bd53a06930b1bf"]}

I thought this was fixed in the 2.3.1. will have to double check. It's supposed to prefix by 0x

[almindor]

Seems I lost this change somewhere in the ew-node module. I'll update and release a new version by EOD tomorrow.

[UGatgithub]

Good somebody else ran in the same issue and you found the root cause now! Also for me it was in Sent: {"id":18,"jsonrpc":"2.0","method":"eth_getTransactionByHash","params":["05112f62832bf9a0f05c12e2ef08ac2fff5dbb672599f8c8964d263d2e318290"]}
Maybe you had overlooked that in my original post.

[almindor]

2.3.2 released with fix, re-open if you still get the issue.
