⚠ Getting a CORS / fetch error? Read this

The chart runs in your browser, so the browser fetches NASDAQ.db directly from S3. S3 will block the read unless the bucket allows cross-origin requests. Since you own hive-in-the-cloud, add this CORS rule in S3 → bucket → Permissions → Cross-origin resource sharing (CORS):

[
                {
                "AllowedHeaders": ["*"],
                "AllowedMethods": ["GET", "HEAD"],
                "AllowedOrigins": ["*"],
                "ExposeHeaders": [],
                "MaxAgeSeconds": 3000
                }
                ]

Or via CLI: aws s3api put-bucket-cors --bucket hive-in-the-cloud --cors-configuration file://cors.json

The object also needs to be readable (public-read, or via a presigned URL pasted into the box above). For tighter security you can replace "*" in AllowedOrigins with the exact origin shown in your browser's console error.
