Policy json is invalid, error: [$[0].Rules[0].Permission[4]: does not have a value in the enumeration. [aoss:CreateIndex]

Question

Trying to: Create a vector index and add permissions to my policy.

Two issues:

1. When trying to a create a vector index I get Failed to fetch.

2. When trying to add a policy it says my JSON is invalid. But all I did was to add more Permissions.

    [
      {
        "Rules": [
          {
            "Resource": [
              "collection/easy-vector-search-collection"
            ],
            "Permission": [
              "aoss:CreateCollectionItems",
              "aoss:DeleteCollectionItems",
              "aoss:UpdateCollectionItems",
              "aoss:DescribeCollectionItems",
              "aoss:CreateIndex",
              "aoss:DeleteIndex",
              "aoss:UpdateIndex",
              "aoss:DescribeIndex",
              "aoss:ReadDocument",
              "aoss:WriteDocument"
            ],
            "ResourceType": "collection"
          }
        ],
        "Principal": [
          "arn:aws:iam::example_id:user/example_user"
        ],
        "Description": "Rule 1"
      }
    ]
