NextJS example Issue in Human In The Loop Mode

### Bug Report: Wallet Connection Issue in Human In The Loop Mode

**Description**
When running the Next.js example in **Human In The Loop** mode, the app sometimes encounters issues after the first startup and wallet connection.

After connecting the Hashpack wallet (via both WalletConnect modal and Hashpack browser plugin), the app displayed a horizontal line instead of the expected account ID. Additionally, attempting to write to the agent resulted in errors.

Refreshing the page resolved the issue.

I was unable to reproduce this issue consistently after the initial occurrence.

**Environment Variables**

> Note:
> In `NEXT_PUBLIC_AGENT_MODE=human`, the `HEDERA_OPERATOR_ID` and `HEDERA_OPERATOR_KEY` are technically not required, but this was the configuration in which the issue was encountered.
