Dropdown with prefered default value

[fafayqa]

I have created a small node which also contains a dropdown menu for all available VAE in ComfyUI, but I would like to set some default value yet the way I am doing it now is not working, can anyone tell me how to do it, please?

This is my code created with help of a "messy" ChatGPT, just the INPUT section that matters:

@classmethod
    def INPUT_TYPES(cls):
        if not os.path.exists(input_dir):
            return {"required": {"latent": ([],), "vae_name": ([],)}}

        files = [
            f for f in os.listdir(input_dir)
            if os.path.isfile(os.path.join(input_dir, f)) and f.endswith(".latent")
        ]
        
        vaes, default_vae_index = get_vae_list()

        # Výpis iba pre VAE časť
        print(f"[+++++++++] VAE list: {vaes}\n")
        print(f"[+++++++++] Default VAE path: {vaes[default_vae_index]}\n")

        # Predvolený VAE súbor musí byť nastavený podľa indexu
        return {
            "required": {
                "latent": (sorted(files),),
                "vae_name": (vaes, vaes[default_vae_index]),
            }
        }

According to prints to CMD you see there, it detect the vaes correctly, also vaes[default_vae_index] has the correct value, yet it is never set as default in the dropdown menu - why?

Try changing this

"vae_name": (vaes, vaes[default_vae_index]),

to

"vae_name": (vaes, { default: vaes[default_vae_index] }),
