Graphs do not render in PopOS React App

3つの 要素を含む React コンポーネントから始め、報告された Pop!_OS 環境で npm start を使って空白のグラフを再現します。ブラウザーの出力を確認し、source-map 警告がレンダリング失敗に関連しているかどうかを判断します。ハードコードされた円グラフが表示され、原因が文書化されていれば完了です。

I am making a React app using Plotly connected to a flask backend. However, my graphs only display as white squares that when hovered over display the plotly toolbar.

This is a picture of what it looks like: here

When I use the command npm start, I get this message which might have something to do with it:

WARNING in ./node_modules/plotly.js/dist/plotly.js
Module Warning (from ./node_modules/source-map-loader/dist/cjs.js):
Failed to parse source map from '/home/david/Programming/Python-Projects/Investment-Hunter-Web/frontend/node_modules/plotly.js/dist/maplibre-gl-unminified.js.map' file: Error: ENOENT: no such file or directory, open '/home/david/Programming/Python-Projects/Investment-Hunter-Web/frontend/node_modules/plotly.js/dist/maplibre-gl-unminified.js.map'

Can anyone help me figure out why my plotly graphs are not displaying at all?

My code seems relatively straightforward as I hard coded the numbers to begin with just to get something going:

import React from 'react';
import Plot from 'react-plotly.js'

function Portfolio() {
    const growthPortfolio = [{
            values: [19, 26, 55],
            labels: ['Residential', 'Non-Residential', 'Utility'],
            type: 'pie',
            hole: 0.4,
    }]

    const valuePortfolio = [{
            values: [30, 40, 30],
            labels: ['Residential', 'Non-Residential', 'Utility'],
            type: 'pie',
            hole: 0.4,
    }]


    const totalPortfolio = [{
            values: [45, 35, 20],
            labels: ['Residential', 'Non-Residential', 'Utility'],
            type: 'pie',
            hole: 0.4,
    }]


    return (
        <div>
            <Plot data={growthPortfolio} />
            <Plot data={valuePortfolio} />
            <Plot data={totalPortfolio}/>
        </div>
    );
}

export default Portfolio;
