Hi all,

I am developing an application using webpack and react. I was able to view successfully.

but I get an error when I use search params specific to the application.


how can i solve this problem.
Thank you

Webpack config =>

const path = require('path');
const HTMLWebpackPlugin = require('html-webpack-plugin');
const cesiumSource = 'node_modules/cesium/Source';
const cesiumWorkers = '../Build/Cesium/Workers';

}

From the error, it looks like CESIUM_BASE_URL is not being set correctly. Based on the [recommended webpack config[(cesium-webpack-example/webpack.config.js at main · CesiumGS/cesium-webpack-example · GitHub), you may want to set this to:

CESIUM_BASE_URL: JSON.stringify('')
