Conversation API not working

[timderspieler]

Expected behavior

The Conversation API working correctly.

Observed/Actual behavior

This bug already has been reported under: https://github.com/PaperMC/Folia/issues/24

After nearly a year I'd like to ask if there are any news regarding the broken Conversation API of Folia. Beginning a new conversation with a player results in the chat being broken. No message can be send anymore upon restarting the server.

Steps/models to reproduce

Player player = getPlayer();

player.beginConversation(new Conversation(SimplePlugin.getInstance(), player, new ValidatingPrompt() {

    @Override
    public String getPromptText(ConversationContext context) {
        context.getForWhom().sendRawMessage("Dopice");

        return "Type anything";
    }

    @Override
    protected boolean isInputValid(ConversationContext context, String input) {
        return false;
    }

    @Override
    protected Prompt acceptValidatedInput(ConversationContext context, String input) {
        return Prompt.END_OF_CONVERSATION;
    }
}));

Plugin and Datapack List

Folia version

That API is currently in a weird state due to the fact that it relies upon legacy behaviours, it's not currently planned on what we want to do for it on paper, and so I'd imagine it's at a much lower priority for folia to resolve this as part of the 20 other dozen APIs which are currently missing

Thank you for the fast reply @electronicboy! Thats unfortunate but Folia's standpoint on this is understandable.
