Trendline not rendered for time scale

[GauntletPL]

Hi,

With the chart configuration like below, I get the following error:

new Chart(
        document.querySelector('#test-trendline'),
        {
            type: 'line',
            data: {
                datasets: [
                    {
                        label: 'Dataset',
                        data: [
                            {date: new Date(2025, 0, 1), val: 10},
                            {date: new Date(2025, 0, 2), val: 20},
                            {date: new Date(2025, 0, 7), val: 30},
                            {date: new Date(2025, 0, 12), val: 10},
                            {date: new Date(2025, 0, 13), val: 40},
                        ],
                        parsing: {
                            xAxisKey: 'date',
                            yAxisKey: 'val'
                        },
                        trendlineLinear: {
                            colorMin: '#0000ff',
                            colorMax: '#0000ff',

                            xAxisKey: 'date',
                            yAxisKey: 'val',
                            projection: true
                        }
                    }
                ]
            },
            options: {
                scales: {
                    xAxis: {
                        type: 'time',
                        time: {
                            unit: 'day'
                        }
                    }
                },
                plugins: {
                    datalabels: false
                }
            }
        }
    );

Try to add
chartjs-adapter-date-fns
and change options to this

options: { scales: { x: { type: 'timeseries', } } }

I am already using chartjs-adapter-luxon. And using timeseries scale isn't something that I'm really after.
Still, applying both changes you've proposed did not fix the problem for me.
