[Bug]: attrs json object in heading does not have Object prototype

[emil14]

Which packages did you experience the bug in?

tiptap-core

What Tiptap version are you using?

2.1.13

What’s the bug you are facing?

Looks like attrs object (e.g. {level: 1} in my case) does not have Object as it's prototype and as a result calling attrs.hasOwnProperty will throw exception.

Can't you just do something like Object.prototype.hasOwnProperty(attrs, 'level') you may ask? No, I'm not the one who do it. I use a library rxdb and

I created an issue in their repo but I think this should be fixed on both sides. There could be many more such cases.

This issue is critical for my app so if they won't fix it it would be awesome if you will. Please help. Thank u!

Also hit attrs not having a prototype, it breaks serialization of docs in my project.

This is causing issues with next.js/react server actions as well. Next.js uses getPrototypeOf when resolving a JSON payload and missing Object prototype is causing exceptions.

Are you saying that this.editor.getJSON() does not actually return JSON? i.e. it is creating objects with a null prototype?

How are you accessing this values?

I am using getJSON(). Yes, it seems like attrs object for headings is created with a null prototype.

Ah okay, well this is because you are calling prosemirror's API for this. This is not an issue with tiptap per se but the underlying library. Honestly I would just JSON.parse(JSON.stringify(attrs.getJSON())) which should give you a straight json object
