BABEL error when configuring with babel.config.js and with typescript preset

[jackgeek]

• babel-plugin-codegen version: 4.1.4
• node version: v12.15.0
• npm version: 6.14.11

With these files:

index.js

// @codegen
module.exports = `console.log("hello world!")`;

babel.config.js

module.exports = {
  presets: ['@babel/preset-typescript'],
  plugins: ['codegen'],
};

I ran this command:

babel --plugins codegen index.js

and got this result:

Error: [BABEL] unknown: Configuration contains string/RegExp pattern, but no filename was passed to Babel

Problem description:

When using a babel.config.js file the above error occurs, however works fine if you change it to a .babelrc file. Also when you remove the typescript preset it works fine.

Sorry I just realized that I should upgrade babel to the latest in my Proof of Bug repo. I have done this and now I get a different error:

Error: /home/jallan/dev/codegen/index.js: [BABEL] unknown: Preset /* your preset */ requires a filename to be set when babel is called directly,
``
babel.transform(code, { filename: 'file.ts', presets: [/* your preset */] });
``
See https://babeljs.io/docs/en/options#filename for more information.

I have pushed the changes to the repo
