### What Operating System are you using (both controller, and any agents involved in the problem)?

Linux

### Reproduction steps

1. Step-1: Provision the google agent.
2. Step-2: Once the Agent reaches timeout it should be removed and deleted automatically.
The above steps are working fine with plugin version 4.703.v43c3a_b_d0e284

### Expected Results

Once the Agent reaches timeout, it should be removed and deleted automatically.

### Actual Results

The agent should be removed after the idle timeout is met.

### Anything else?

We noticed a weird warning with the agent.
