Prevent y-axis labels from being cut off

My chart y labels are cut off and by trying different solution found on stackoverflow like adding spaces in labels or setting layout padding did not solved the problem.

The code

const optionsTotali = {
  maintainAspectRatio: false,
  responsive: true,
  plugins: {
    legend: {
      display: false
    },
    tooltip: {
      displayColors: false,
      mode: "index",
      intersect: 0,
      callbacks: {
        label: function(context) {
          return "€" + context.parsed.y.toFixed(2).replace(/\d(?=(\d{3})+\.)/g, '$&,').replace(/[,.]/g, m => (m === ',' ? '.' : ','));
        }
      }
    },
  },
  scales: {
    y: {
      grid: {
        display: false
      },
      ticks: {
        min: 0,
        beginAtZero: true,
        sampleSize: 1,
        callback: function(value, index, values) {
          return "€" + value.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ".");
        }
      }
    }
  }
};

const ctx = document.getElementById("chartTotali").getContext('2d');
const chartTotali = new Chart(ctx, {
  type: 'line',
  data: {
    labels: [
      "08:00",
      "09:00",
      "10:00",
      "11:00",
      "12:00",

      "16:00",
      "17:00",
      "18:00",
      "19:00",
      "20:00"
    ],
    datasets: [{
      label: "Totale €",
      fill: true,
      backgroundColor: '#0084ff',
      borderColor: '#0084ff',
      borderWidth: 2,
      pointBackgroundColor: '#0084ff',
      data: [

        "138158.94",
        "398.46"
      ],
    }]
  },
  options: optionsTotali
});
.card-chart {
  overflow: hidden;
