Cardano-wallet: account syncing error

[lijianl]

my account's syncing was blocked by error below:

[cardano-wallet.wallet-engine:Error:5452] [2020-08-03 06:41:30.34 UTC] 5180708f: Unexpected error following the chain: ExceptionInLinkedThread ThreadId 125077 DecoderFailure (ChainSync (ByronBlock) (Tip ByronBlock)) ServerAgency TokNext TokCanAwait) (DeserialiseFailure 1015 "Found unknown tag 2 while decoding Block") from cardano-wallet

and cardano-node log error:
[nuls-nov:cardano.node.LocalErrorPolicy:Error:54] [2020-08-03 06:42:11.18 UTC] [String "ErrorPolicyUnhandledApplicationException (MuxError (MuxIOException writev: resource vanished (Broken pipe)) \"(sendAll errored)\")",String "ErrorPolicyTrace",String "LocalAddress {getFilePath = \"\"}"]

my byron-wallet syncing was blocked at 99.58 ....? what are the meanings of error from log.

I build cardano-node from master,
git clone https://github.com/input-output-hk/cardano-node.git cd cardano-node nix-build -A scripts.mainnet.node -o mainnet-node-local && ./mainnet-node-local and build cardano-wallet from master too:
git clone https://github.com/input-output-hk/cardano-wallet.git nix-build -A cardano-wallet-byron cardano-wallet serve --node-socket ~/cardano-node/state-node-mainnet/node.socket --mainnet --database /tmp/mainnet
and restore my wallet with API below
POST http://xxx.xxx.xxx.xxx:8091/v2/byron-wallets.
then wallet syncing met error. what happened? and the meaning of the error

[lijianl]

I have some ADA in my wallet, and the wallet is not available since syncing blocked.
it is very urgent for me, could you guys help me with these error..

Hi, the mainnet has _forked_ since July 29th to a new Era. Therefore, you need to use a version of the wallet that is compatible with this new era. We're in the process of removing cardano-wallet-byron, in the meantime, you ought to use cardano-wallet-shelley.

Cheers.

how to build cardano-wallet from source to support Shelley ERA? could you give some link or tips to move wallet from byron to shelley

could you give some links to introduce how to move to new ERA with source code

[lijianl]

cardano-wallet only provided byron type nix-build -A cardano-wallet-byron, any building way for shelley with source code

cardano-wallet only provided byron type nix-build -A cardano-wallet-byron, any building way for shelley with source code

Have you tried:

$ nix-build -A cardano-wallet-shelley

You might want to check that you've pulled the latest changes to the cardano-wallet repository, or just clone it again from scratch.

[lijianl]

thanks for your replay, I will try it

[lijianl]

hello.
I build cardano-wallet with nix-build -A cardano-wallet-shelley;

however it is impossible to retore byron-wallet into shelly, it happened "message": "Error in $['mnemonic_sentence']: Invalid number of words: 15, 18, 21 or 24 words are expected.", indeed my byron-wallet has 12 words.

what should I do to retore my byron-wallet and resue my ADA from this wallet

[lijianl]

should I build source code with Shelley mode and use API with byron mode? isn't it wired

[KtorZ]

@lijianl, yes. The naming may looks a bit confusing but, the entire API is available now because, the chain isn't just Shelley. The chain is the continuation of Byron -> Shelley. So, blocks, addresses, transactions etc.. are present in BOTH format in the chain. Therefore, anything that existed in Byron still exists after the hard fork. Wallets that existed in Byron and new Shelley wallets have different address formats, but so-called Byron wallets are still valid and exist in the Shelley era as well.

thanks for your reply and I have solved my problem;
Here is the summary:

1. build Cardano-node from source: v-1.18.0
   git clone https://github.com/input-output-hk/cardano-node.git cd cardano-node nix-build -A scripts.mainnet.node -o mainnet-node-local

2. build Cardano-wallet from source: v-1.18.0:

git clone from source nix-build -A cardano-wallet-shelley

1. retore my wallet and serve the wallet with byron-api

Thanks again!
