CORS error in SCORM XBlock

Hi all,

I’m experimenting a CORS error when using a SCORM XBlock in my Tutor K8s - maple. The backend is S3, and the SCORM was unpacked and loaded properly in the bucket by the XBlock in Studio.
In the local installation it is working.

The log shows:

The bucket has public access, and has this CORS configuration:

[
    {
        "AllowedHeaders": [],
        "AllowedMethods": [
            "DELETE"
        ],
        "AllowedOrigins": [
            "https://*my_lms_host*",
            "https://studio.*my_lms_host*",
            "https://preview.*my_lms_host*",
            "https://apps.*my_lms_host*"
        ],
        "ExposeHeaders": []
    }
]

Any idea why can this be?
