Uncaught (in promise) Error: Unable to find messagesWrapperElement

[thoughtsunificator]

Uncaught (in promise) Error: Unable to find messagesWrapperElement

So I take it that based on description of your thread it fails on a two messages thread where both parties sent a single text message?

Uncaught (in promise) Error: Unable to find messagesWrapperElement

So I take it that based on description of your thread it fails on a two messages thread where both parties sent a single text message?

I've tried at least 10-11 different message variations. Other party's texts first or mine, photos, videos, stickers. When I click "Unsend all DMs", it starts but then it goes nowhere. The UI "unsending" is stuck. Console shows this error in the red highlight.

Can you go to one of your test thread, save the web page, make sure there is no personal information and include it here?

Wouldn't saving web page also include personal information? I do not know how to save the web page by excluding all personal info. If the script is working for you, could you tell us how you're using it?

[thoughtsunificator]

We are getting nowhere.

This is the code in debug for error in console*: Uncaught (in promise) Error: Unable to find messagesWrapperElement

	/**
	 * @param {Window} window
	 * @returns {DefaultUI}
	 */
	static create(window) {
		console.debug("UI create")
		const messagesWrapperElement = findMessagesWrapper(window)
		if(messagesWrapperElement !== null) {
			console.debug("Found messagesWrapperElement", messagesWrapperElement)
			const uiMessagesWrapper = new UIMessagesWrapper(messagesWrapperElement)
			return new DefaultUI(window, { uiMessagesWrapper })
		} else {
			throw new Error("Unable to find messagesWrapperElement")
		}
	}

This is what I'm getting under console

I do think this is where the problem is taking place.

If you tell me what region you are using Instagram web client from to see if the changes are region wide since the script is working for you, maybe I could run the script using different network address.
