Stream incorrect or unsupported! AmazonS3 Storage exception

I’ve created AWS S3 bucket and configured a use with IAM role to have read/write access to this bucket.

I’ve created a new storage type AWS S3 and properly everything configured. I’ve confirmed that connection is valid:

However, triggering the conversion with API returns the following error:

{
  "RequestId": "d1f16b0a5e8a9048b55e2111fb367b19",
  "Error": {
    "Code": "internalError",
    "Message": "Stream incorrect or unsupported! AmazonS3 Storage exception: The specified bucket is not valid. Bucket 's3://xxxxx', FilePath 'original/unit-a.jt'",
    "Description": "Operation Failed. Internal error.",
    "DateTime": "2025-12-19T14:54:29.0905602Z",
    "InnerError": null
  }
}

This is the cURL request I’m sending:

curl -X POST "https://api.aspose.cloud/v3.0/3d/saveas/newformat?name=unit-a.jt&newformat=gltf2_binary&newfilename=unit-a.gltf&folder=original&IsOverwrite=true&storage=3D%20Models" -H "accept: application/json" -H "authorization: Bearer xxxx" -H "x-aspose-client: Containerize.Swagger"

What else am I missing?
