[ERROR]:**Error loading entrance module.**
Traceback (most recent call last):

File "/var/log/amazon/ssm/patch-baseline-operations/common_os_selector_methods.py", line 125, in _get_snapshot_info

ssm_client = client_selector.get_default_client(instance_id, region, "ssm")

Answer

Hello,

Please make sure that only one patch task is active on the instance at a time.
This type of error generally occurs when multiple patch tasks are active on an instance.

Hope this helps.

Answer

The error you're encountering seems to be a problem with the Amazon SSM Agent or the Patch Manager script.

Verify the Amazon SSM Agent version:

```
sudo amazon-ssm-agent -version
```

Verify the instance IAM role: Ensure that your EC2 instance has the necessary IAM role and permissions to use Patch Manager

if both does not work for you

please check the agent logs /var/log/amazon/ssm on your instance
