You get this error when ranges is malformed, in my case my object was:

{
    "startDate": "2022-06-01T00:00:00.000Z",
    "endDate": "2022-06-29T00:00:00.000Z",
    "key": "selection"
}

when ranges should be

[
    {
        "startDate": "2022-06-01T00:00:00.000Z",
        "endDate": "2022-06-29T00:00:00.000Z",
        "key": "selection"
    }
]

it should be of type array, not object

Hey, if you using class componenet you should pass the value onChange like this : this.setState({range:[range.selection]})
