Why does AWS S3 GUI put { "_1": } around my JSON file?

I have a valid JSON file which I am uploading to a bucket in AWS S3 directly by using the GUI.

[
    {
        "attribute1" : "foo1",
        "attribute2" : 123,
        "attribute3" : "bar1"
    },
    {
        "attribute1" : "foo2",
        "attribute2" : 123,
        "attribute3" : "bar2"
    }
]

When I use the AWS GUI Select from (preview) with settings File format = JSON, JSON type = JSON lines and Compression = None, I get the following output:

{
    "_1": [
        {
            "attribute1" : "foo1",
            "attribute2" : 123,
            "attribute3" : "bar1"
        },
        {
            "attribute1" : "foo2",
            "attribute2" : 123,
            "attribute3" : "bar2"
        }
    ]
}

Do you have an idea why S3 puts the { "_1": }, around my JSON file?

If you send it like below

{ "attribute1" : "foo1", "attribute2" : 123, "attribute3" : "bar1" } { "attribute1" : "foo2", "attribute2" : 123, "attribute3" : "bar2" }

you can see this s3 json query

[ { "attribute1" : "foo1", "attribute2" : 123, "attribute3" : "bar1" }, { "attribute1" : "foo2", "attribute2" : 123, "attribute3" : "bar2" } ]

good~
