[Bug] staking validator-history fails: "client.getSlashingAddress is not a function"

[Tobu8888]

Description

genlayer staking validator-history throws client.getSlashingAddress is not a function and fails to return any history. All other staking subcommands work fine on the same account/network, so the bug appears isolated to the validator-history code path.

Steps to reproduce

1. Configure the CLI for testnet-asimov with a valid account.
2. Run:

   genlayer staking validator-history --validator 0x9f50DDcd4Af137E14467232490035F13D67998C0

Actual result

⠸ Fetching validator history...
Error:
        client.getSlashingAddress is not a function
✖ Failed to get validator history

Expected result

Returns the validator's slash/reward history (default: last 10 epochs).

Works fine on the same account/network (isolates the bug)

validator-info, epoch-info, active-validators, set-operator, and set-identity all run successfully — only validator-history fails.

Environment

• genlayer-cli: 0.39.1
• Network: testnet-asimov (Asimov Phase 5)
• OS: Linux x86_64
• Node.js: v20.20.2

Additional notes

The error suggests the client object is missing a getSlashingAddress method — possibly renamed/removed in the underlying SDK, or not wired up for the testnet-asimov network in the validator-history path.
