Elements not retrieved from AWS Bucket

[dn-scribe]

Describe the bug
I set up an S3 bucket according the the official data model.
I create a Plotly chart as an element an it is presented.
When refreshing the page I get: "an error occurred" in the UX,
When examining with developer tools I get:

Access to fetch at 'https://my_bucket.s3.amazonaws.com/threads/a8094cf3-34b0-4fd7-9806-e67d01c139c1/files/vulnerability_chart?X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Credential=AKIA6GBMHSSRN3A64FHE%2F20250124%2Fil-central-1%2Fs3%2Faws4_request&X-Amz-Date=20250124T120947Z&X-Amz-Expires=3600&X-Amz-SignedHeaders=host&X-Amz-Signature=51be1afa241c41b25dbf12fb00dc4001a28749002b039f3b1f53382a4baefa03' from origin 'https://my-app.my_org.com' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.

The AWS CORS is set to accept any origin `["*"]'

To Reproduce
Expected behavior
To work.

Screenshots
None.

Desktop (please complete the following information):
Happens both on my Mac in debug mode, and when running on AWS EKS.

Additional context
Things did work properly when using minio an and S3 bucket emulator.

I am getting a similar issue on chainlit v2.0.6 with AWS bucket. I also have allow_origins = ["*"]
