Steps to reproduce

• Bootstrap an application with lisk-commander
• Ensure the dependencies in pacakage.json correspond to Lisk SDK v6.0.0-beta.5
• Ensure all the plugins in src/commands/start.ts are registered with { loadAsChildProcess: true } option
• Install dependencies and build the application
• Ensure to update the node config with the necessary plugin config you intend to enable

	}

• Start the node with the plugin enabled (./bin/run start -n devnet --enable-chain-connector-plugin)

Which version(s) does this affect? (Environment, OS, etc...)

v6.0.0-beta.5

[shuse2]

This is failing specific to chain-connector plugin because when decrypting the private key on init it will stop the initialization too long that it will timeout to create the child process.

Removing the password and below issue will resolve the problem
