React Mapbox layer not showing

I'm trying to use React Mapbox but I'm facing some problems with using the Layer component.

I'm trying to follow this demo: https://github.com/alex3165/react-mapbox-gl/blob/master/example/src/demos/heatmap.tsx

Or even the "quick start" demo from the main page: https://github.com/alex3165/react-mapbox-gl

And my map is showing but the layer is doesn't! Here's my code:

import React, { useState } from "react";
import ReactMapboxGl, { Layer, Feature, ZoomControl, Marker } from "react-mapbox-gl";
import "mapbox-gl/dist/mapbox-gl.css";
const data = require("./heatmapData.json");

function LiveMap(props) {

  const Map = ReactMapboxGl({
    accessToken: "pk.ey",
  });

  const heatmapPaint = {
    "heatmap-weight": {
      property: "priceIndicator",
      type: "exponential",
      stops: [
        [0, 0],
        [5, 2],
      ],
    },
    // Increase the heatmap color weight weight by zoom level
    // heatmap-ntensity is a multiplier on top of heatmap-weight
    "heatmap-intensity": {
      stops: [
        [0, 0],
        [5, 1.2],
      ],
    },
    // Color ramp for heatmap.  Domain is 0 (low) to 1 (high).
    // Begin color ramp at 0-stop with a 0-transparancy color
    // to create a blur-like effect.
    "heatmap-color": [
      "interpolate",
      ["linear"],
      ["heatmap-density"],
      0,
      "rgba(33,102,172,0)",
      0.25,
      "rgb(103,169,207)",
      0.5,
      "rgb(209,229,240)",
      0.8,
      "rgb(253,219,199)",
      1,
      "rgb(239,138,98)",
      2,
      "rgb(178,24,43)",
    ],
    // Adjust the heatmap radius by zoom level
    "heatmap-radius": {
      stops: [
        [0, 1],
        [5, 50],
      ],
    },
  };

  return (
    <section>
      {/* block */}
      <div className="p-5 rounded-lg">
        {/* map */}
        <Map
          className="h-half rounded-lg shadow-lg z-0"
          style="mapbox://styles/mapbox/streets-v9"
          center={[-0.481747846041145, 51.3233379650232]}
        >
          <ZoomControl />
          <Layer type="heatmap" paint={heatmapPaint}>
            {data.map((el, index) => (
              <Feature key={index} coordinates={el.latlng} properties={el} />
            ))}
          </Layer>

          <Layer type="symbol" id="marker" layout={{ "icon-image": "marker-15" }}>
            <Feature coordinates={[-0.481747846041145, 51.3233379650232]} />
          </Layer>
        </Map>
      </div>
    </section>
  );
}

export default LiveMap;

I can't understand why my heatmap or my symbol is not showing on the map. What I'm doing wrong?

Same happened to me, this issue also applies to Zoom Control and markers. react-mapbox-gl version 5.0.0 has issues to solve yet.

Ok, so after some more research I found that the problem is in the last version of react-mapbox-gl (5.0.0). Installing [email protected] finally displayed my Layers and everything works fine. I don't know what is the problem in version 5.0.0. Hope they will fix this soon.
