Error when creating kitty #7

Closed jimmychu0807 closed 2 months ago

jimmychu0807 commented 4 years ago

On the latest v2.0 branch, when creating kitty from polkadot-JS app, it returns in the browser dev-console:

RPC-CORE: submitAndWatchExtrinsic(extrinsic: Extrinsic): ExtrinsicStatus:: 1002: Verification Error: Execution: Could not convert parameter `tx` between node and runtime: Error decoding field CheckEra.0: Client(Execution(ApiError("Could

The runtime console:

2019-11-27 16:34:06 Idle (0 peers), best: #50 (0x95d8…39c0), finalized #48 (0x45ff…1a14), ⬇ 0 ⬆ 0
2019-11-27 16:34:09 Failed to submit extrinsic: Extrinsic verification error: Execution: Could not convert parameter `tx` between node and runtime: Error decoding field CheckEra.0

I and @kaichaosun encounter this issue.

We've been discussing this issue in the Substrate Technical (Public) Riot chatroom. It's because all the dependencies are being build from an old commit dated 25th October in the 'master' branch of the Substrate repo. I've got it to work by using the latest commit instead (i.e. progressively going through all the commits since then and getting it to compile), and then checking that it was consistent with the https://github.com/paritytech/substrate/tree/master/bin/node-template

I'll create a PR with the changes I had to make. Unfortunately I've got a poor wifi connection so building it to check it works may need to wait until tomorrow when I'm in the office

Solution: https://github.com/ltfschoen/substratekitties/tree/v2.0

Noting that this fix likely won't get merged, see https://matrix.to/#/!HzySYSaIhtyWrwiwEV:matrix.org/$1574898806602KyvWj:matrix.parity.io?via=matrix.parity.io&via=matrix.org&via=web3.foundation
