Error when providing axis tickformat, but dataset is empty

I could not find this anywhere in reported/open/closed problems, so here goes.
I'm dynamically fetching my dataset for plotly - and sometimes there is no data - a normal condition for my app.
When providing a timestamp-like xaxis tickformat, an error will occur when the dataset is empty.

  Plotly.newPlot(this.chartTarget.id, {
    data: [
      { name: "Spot", type: "scatter", mode: 'lines', x: [], y: [], line: {color: 'black'} },
    ],
    layout: {
      title: "Blah",
      hovermode: "closest",
      hoverlabel: { bgcolor: "#FFF" },
      legend: { orientation: 'h', y: -0.3 },
      xaxis: { tickformat: "%H:%M", title: {text: "Time", automargin: true, standoff: 0}, zeroline: false },
      yaxis: { title: "YAxis" }
    },
    config: { responsive: true }
  });

When the dataset is empty alike above (and only when empty), a JS error will be thrown with a trace that looks like:

console.trace() WARN: encountered bad format: "%H:%M" plotly-finance.js:27425:18

It seems like the format handler should be able to detect this situation and avoid the error when there's actually nothing to format in the first place.

Thanks for consideration and hopeful for a resolution within plotly itself for this potentially-expected condition.

Riproduci la chiamata Plotly.newPlot fornita con array x e y vuoti e xaxis tickformat "%H:%M". Parti dalla chiamata newPlot e dalle voci dello stack relative alla formattazione in plotly-finance.js, quindi conferma che un set di dati vuoto non produca più l’errore bad-format.
