Blog tutorial fails when using feat/sdk-ibc-upgrade branch

[jeronimoalbi]

This issue is related to #2677

Description

The blog tutorial fails when the app is initialised with the error:

Cosmos SDK's version is: stargate - v0.46.0

🛠️  Building proto...
📦 Installing dependencies...
🛠️  Building the blockchain...
💿 Initializing the app...
json: cannot unmarshal string into Go value of type []chaincmdrunner.Account

To reproduce

• Checkout the feat/sdk-ibc-upgrade and compile Ignite CLI using make
• Scaffold the blog chain app: ignite scaffold chain blog
• Add a replace statement to the blog/go.mod so the chain app uses the local CLI repository (the path may be different for you): replace github.com/ignite/cli => ../cli
• Start the chain: ignite chain serve

I've got the same error:
Cosmos SDK's version is: stargate - v0.46.1

🛠️ Building proto...

🛠️ Building the blockchain...
💿 Initializing the app...
json: cannot unmarshal string into Go value of type []chaincmdrunner.Account

Anyone have any ideas to solve it. Thanks

Thanks @dungtran8tiki, would you add a comment with the output you get when running ignite version?

Also it would be great if you could give more context that would help us to reproduce the issue.

My ignite version:
Ignite CLI version: development
Ignite CLI build date: 2022-10-01T15:56:18
Ignite CLI source hash: 6995021
Your OS: darwin
Your arch: amd64
Your go version: go version go1.19.1 darwin/amd64
Your uname -a: Darwin LAP02459s-MacBook-Pro.local 21.6.0 Darwin Kernel Version 21.6.0: Mon Aug 22 20:20:05 PDT 2022; root:xnu-8020.140.49~2/RELEASE_ARM64_T8101 x86_64
Your cwd: /Users/lap02459/sourcecode/aliassend
Is on Gitpod: false

How to produce this error:

1. Using Ignite to create a simple chain
2. in go.mod update as follows
   replace (
   github.com/cosmos/cosmos-sdk => /Users/lap02459/sourcecode/localCosmos-sdk
   github.com/gogo/protobuf => github.com/regen-network/protobuf v1.3.3-alpha.regen.1
   )
3. in codec.go
   replace
   var (
   Amino = codec.NewLegacyAmino()
   ModuleCdc = codec.NewProtoCodec(cdctypes.NewInterfaceRegistry())
   )
   by
   var (
   Amino = codec.NewLegacyAmino()
   ModuleCdc = codec.NewAminoCodec(Amino)
   )

func init() {
RegisterCodec(Amino)
cryptocodec.RegisterCrypto(Amino)
}

note: please import --- cryptocodec "github.com/cosmos/cosmos-sdk/crypto/codec"

Using "ignite chain build" then build ok, run "ignite chain serve" for the first time might be ok. But stop and re-run "ignite chain serve" will get "json: cannot unmarshal string into Go value of type []chaincmdrunner.Account"

Hello @jeronimoalbi ,
when I use ignite to create a new chain on different folder but the same name. I delete ~/.<chain_name>. Then "ignite chain serve" also raise the error "json: cannot unmarshal string into Go value of type []chaincmdrunner.Account". I wonder that ignite stored some environment variables (or config parameters for this chain) some where else? Please give me some hint to solve this issue. Thank you

[dungtt-astra]

Debugging ignite source code, I found that CheckAccountExist() return error, since it cannot find the keys for account in config.yml.
To fix it, we simply re-create account. <yourchain_name> keys add <account_name>

@dungtran8tiki I didn't manage to reproduce the issue, out of curiosity what branch or tag are you using in /Users/lap02459/sourcecode/localCosmos-sdk?

[dungtt-astra]

it's cosmos-sdk, I put it at my local computer to add some debug log to track&learn code flow of cosmos.
