Ensure type: module in package.json

Added this in craco.config.js webpack object:

configure: {
      module: {
        rules: [
          {
            test: /\.m?js/,
            resolve: {
              fullySpecified: false
            }
          },
        ],
      },
},

Modify package.json scripts.test:

"test": "NODE_OPTIONS=--experimental-vm-modules craco test",
