How to fix it?

[krugerpao]

hello, I get same problem,
I have 2 copy SD int D:\A & D:\B
when A run this error ( yes, after generating images fail),
I find some file in A changed Date,
so I copy B ui-config.json and config.json to A, Then A work Back!
I don't know why , But it's work , FYI! : )

[linuxdevopscn]

I also encountered the same problem. When I printed filename, I found that the file was config.json. When I checked the json file, I found that the file was corrupted. I deleted config.json and restarted the service, which was able to run successfully, but some of my previous configurations were lost and restored to default configurations. I don't know why this file was corrupted.

What is causing this?

loading settings: JSONDecodeError Traceback (most recent call last): File "F:\Programs\Stable Diffusion WebUI\webui\modules\ui_loadsave.py", line 30, in __init__ self.ui_settings = self.read_from_file() File "F:\Programs\Stable Diffusion WebUI\webui\modules\ui_loadsave.py", line 132, in read_from_file return json.load(file) File "json\__init__.py", line 293, in load File "json\__init__.py", line 346, in loads File "json\decoder.py", line 337, in decode File "json\decoder.py", line 355, in raw_decode json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

[CirnoChan999]

Solved it by deleting some config files.
This will reset all of the settings you've set before.
You might want to check if one of the files has size 0, that might be the only file that needs to be deleted.

These are the files I deleted:

1. ui-config.json
2. cache.json
3. config.json

All of these files are generated again while the Automatic1111 is running.
The config.json is generated only after you save your settings once.

Good luck.
