None Character Error

[TheCyberViking]

Describe the bug

I had no issues before a recent update. I performed an update to the latest version, and now I have the error popping up "ERROR:Could not find the character "None" inside characters/. No character has been loaded.". I was able to solve the issue using the character card which was a simple assistant and called it none.json, A good chance of a simple fix would be to have a character that is a simple assistant named None pre-loaded into the character folder on update or download

Is there an existing issue for this?

Reproduction

update and try Loading the Web-UI or refreshing the Web-UI causes the error to popup

Yeah I have the exact same error. It loads my character card and everything is working fine but the error message is a bit annoying every start.

[Mathias9807]

I had this error too and apparently my config was the issue. In settings.yaml the character field had a value of "None"... Solved by setting it to "Assistant".

[arleas]

I'm getting this same error except instead of "none" it's "[]" (Open and close brackets). I don't know what else to do but make a fake character named "[]" but eventually it crashes gradio...

[showkeyjar]

same +1

[ratzycon]

getting this as well,

first thought it was a image cache problem when characters starts to have wrong portraits, but it seems like there might be a parsing error or something in the json chat log

Could not find the character "[]" inside characters/. No character has been loaded.

This error is an error that comes out when reloading because the character value is not received properly.

Fix file "text-generation-webui/modules/chat.py Line 661"

def load_character(character, name1, name2):
    context = greeting = ""
    greeting_field = 'greeting'
    picture = None

to

def load_character(character, name1, name2):
    if character is None or (not character):
        character = 'Assistant'

    context = greeting = ""
    greeting_field = 'greeting'
    picture = None

It works for me
