Index out of bounds in brupop-agent in agent/src/apiclient.rs:237:89

**Image I'm using: 1.6.0**
**Bottlerocket OS I'm using: bottlerocket-aws-k8s-1.32-x86_64-v1.39.0-0968c061**

**Issue:**

Hello, the brupop-agent crashes with a panic in agent/src/apiclient.rs:237:89 due to an index out of bounds: the len is 1 but the index is 1 error.

> thread 'main' panicked at agent/src/apiclient.rs:237:89:
index out of bounds: the len is 1 but the index is 1

I couldn´t figure out why this error occured, it worked for weeks until now. Bottlerocket is new to me.

if I enable DEBUG via values.yml I get these before the container dies:
