[3.0.4][Remote Logging] "Unable to find AWS Connection ID" under KubernetesExecuotor configuration

[hcnhcn012]

airflow version: 3.0.4
deployment method: helm
executor: KubernetesExecuotor

---

I noticed this issue was happened in former versions and it should be fixed in 3.0.4 (see: #50583), but it still happend for me when i upgrade airflow version by changing helm value:

defaultAirflowTag: "3.0.4"
airflowVersion: "3.0.4"

I can confirm that the aws connection was created correctly (checked airflow connections list), but the worker pod can not find this connection. Here is my configuration.
