[Bug]: T2I with multi-controlnet canny and HED throws `AttributeError: 'NoneType' object has no attribute 'split'`

[oliverban]

Is there an existing issue for this?

• [X] I have searched the existing issues and checked the recent builds/commits of both this extension and the webui

What happened?

Tried to render in t2i with controlnet set to Canny and HED, which worked fine with one. But then I added a second one with Guess Mode and got this: Traceback (most recent call last): File "C:\Users\olive\Documents\stable-diffusion-webui\venv\lib\site-packages\gradio\routes.py", line 337, in run_predict output = await app.get_blocks().process_api( File "C:\Users\olive\Documents\stable-diffusion-webui\venv\lib\site-packages\gradio\blocks.py", line 1013, in process_api inputs = self.preprocess_data(fn_index, inputs, state) File "C:\Users\olive\Documents\stable-diffusion-webui\venv\lib\site-packages\gradio\blocks.py", line 911, in preprocess_data processed_input.append(block.preprocess(inputs[i])) File "C:\Users\olive\Documents\stable-diffusion-webui\extensions\sd-webui-controlnet\scripts\controlnet.py", line 361, in svgPreprocess return input_image.orgpreprocess(inputs) File "C:\Users\olive\Documents\stable-diffusion-webui\venv\lib\site-packages\gradio\components.py", line 1508, in preprocess mask_im = processing_utils.decode_base64_to_image(mask) File "C:\Users\olive\Documents\stable-diffusion-webui\venv\lib\site-packages\gradio\processing_utils.py", line 53, in decode_base64_to_image content = encoding.split(";")[1] AttributeError: 'NoneType' object has no attribute 'split'

Steps to reproduce the problem

1. Go to t2i
2. write some words like sword, helmet
3. Select Canny for cn1 and HED for cn2 and then have Guess Mode on for cn1
4. Hit generate

What should have happened?

A render should have gone through and started showing me a render

I am actually experiencing this exact same problem.

I am facing the same problem but with only Canny model.
