I’m getting the following despite my code seeming sane:

aws:s3:BucketObject (index.html):
    warning: urn:pulumi:dev::admin::aws:s3/bucketObject:BucketObject::index.html verification warning: use the aws_s3_object resource instead
    error: aws:s3/bucketObject:BucketObject resource 'index.html' has a problem: Attribute must be a single value, not a map. Examine values at 'index.html.bucket'.
