Splunk 9.1.3 Startup Errors

Hello,

We recently upgraded from 9.0.7 to 9.1.3 for the Universal Forwarder using the image provided here

The errors we see are:

TASK [splunk_universal_forwarder : Debug hec_token] ****************************
ok: [localhost] => {
    "hec_token": {
        "changed": true,
        "excep_str": "No Exception",
        "failed": false,
        "json": {
            "messages": [
                {
                    "text": "Could not find object id=http://splunk_hec_token/",
                    "type": "ERROR"
                }
            ]
        },
        "status": 404
    }
}

Which looks like it gets resolved with:

TASK [splunk_universal_forwarder : Debug create_hec_token] *********************
ok: [localhost] => {
    "create_hec_token": {
        "changed": false,
        "skip_reason": "Conditional result was False",
        "skipped": true
    }
}

We're not using HEC in this case so I think this error can be ignored.

We then see this error happen twice:

We still see events being forwarded and things appear to look okay. Is there anything else I should check or be concerned about?
