WeakMap expected key

[kevcomparadise]

Hello,

I've been using PostRobot for a while. I use it to communicate with my application when implementing it in an iframe. I am on Nuxt2, and it works very well.

I am currently migrating to Nuxt3 and encountering an issue. When importing the library (on the client side), I get an error like this:

"WeakMap expected key."

I don't understand why, as I have the window variable accessible.

Thank you for your help.

Same issue. Can work around it via if you import the browser version directly. Hope it saves some time to someone.

  // nuxt.config.ts
  app: {
    head: {
      // make sure to match your iframe version, @krakenjs scoped package doesn't work with this one...
      script: [{ src: 'https://unpkg.com/post-robot@10.0.46/dist/post-robot.min.js' }], 
    },
  },

// global.d.ts at root nuxt folder
import PostRobot from 'post-robot'

export {}

declare global {
  interface Window {
    __NUXT__: any
    postRobot: typeof PostRobot
  }
}
