try set Add hypernetwork to prompt to None

Thank you for your help, I’ve solved it~!

I have this exact same issue but the above – which was and is set to None – didn't solve it for me. Anyone else?

set None, click Refresh button, apply&restart

I have the same issue. For me the Add hypernetwork to prompt setting was already set to None, and simply setting this setting again, saving, and restarting didn't help.

Here is my full error:

activating extra network lora: TypeError
Traceback (most recent call last):
  File "...edited...\stable-diffusion-webui\modules\extra_networks.py", line 145, in activate

TypeError: 'NoneType' object is not iterable

Under User Interface > Quick Settings I have the sd_lora option to show a drop down menu for Lora models (next to checkpoints menu - top of the screen). With this setting, when I start SD, and when a previously used Lora loads from a previous session, this error occurs. When this additional drop menu is set to None, the error does not occur.

Additionally, if the sd_lora option is removed with a Lora model chosen, the error will persist until this setting is restored back to None. I actually had to re-add the sd_lora option in order to clear the drop menu to do this.

Seems like a minor bug.

I had the same issue : the culprit was the following (also mentioned by @TheArkive ) :

More precisely : I had a LORA selected that wasn't compatible/corrupted or otherwise, experienced some strange behaviour (even when specified in the prompt)

I just change the model name to lcm-lora-sdxl.safetensors and everything works
