addBabelPlugins is not working

In CRA3, I get an error of typescript namespace which is

Non-declarative namespaces are only supported experimentally in Babel.

look like I need @babel/plugin-transform-typescript to resolve it, but I add it uses addBabelPlugins still get this error.

module.exports = config => {
  const {
    entry,
    resolve = {},
    module: {rules},
  } = config;
  const {alias = {}} = resolve;
  // find index of eslint rule
  const findRuleIndex = cb => rules.findIndex(rule => cb(rule));
  const eslintRuleIndex = findRuleIndex(
    ({use}) => use && /eslint/.test(use[0].loader),
  );

  config.module.rules.splice(eslintRuleIndex, 1);
  config.entry.pop();
  config.entry = [...entry, Path.resolve('./src/app/index.tsx')];

  return override(
    addWebpackAlias({
      ...alias,
      '~': Path.resolve('src/app'),
      '~imgs': Path.resolve('src/app/assets/static'),
    }),
    ...addBabelPlugins([
      '@babel/plugin-transform-typescript',
      {allowNamespaces: true},
    ]),
  )(config);
};

This is my override config file.

This is weird… I use a minimal config with:

const {
    override,
    addExternalBabelPlugin
  } = require("customize-cra");

module.exports = override(
    addBabelPlugin([
        "@babel/plugin-transform-typescript",
        { allowNamespaces: true }
    ])
);

but Babel acts as if the option allowNamespaces wasn’t there…

@youncccat Did you figure it out?
