better_combos: encoded url and substring not found

[universorum]

Whan add the Lora Loader node, the console will hint substring not found error.

ValueError: substring not found

The problem is the variable name is encoded uri that mean the / will be encoded to %2F. We should call urllib.parse.unquote before find the index of /.

yes，it works. Adding 'name = parse.unquote(name)' after 'name = request.match_info["name"]'

[Moxie1776]

yes，it works. Adding name = parse.unquote(name) after name = request.match_info["name"]

I opened this up in vscode to search for all instances of name = parse.unquote(name), implemented this fix in multiple places across 3 different files, and it did fix all the issues I'm having. Thanks :) Note: added from urllib import parse

For those coming across this issue, this solution worked for me as well, I'll try to explain the solution in a bit more detail for those who aren't as well versed in modifying python code (like me).

Go to this folder _...\ComfyUI_windows_portable\ComfyUI\customnodes\ComfyUI-Custom-Scripts\py There are two files that needs to be modified; "better_combos.py" and "model_info.py" Open these files with your preferred text editor like, notepad.

At the top of each file there will be text like this:

import glob
import os
from nodes import LoraLoader, CheckpointLoaderSimple
import folder_paths
from server import PromptServer
from folder_paths import get_directory_by_type
from aiohttp import web
import shutil

At the end add this text: from urllib.parse import unquote

it should look like this:

from folder_paths import get_directory_by_type
from aiohttp import web
import shutil
from urllib.parse import unquote

Then in each document look for all places where you can find these lines (you can use your text editors search function or just have a look yourself):

    name = request.match_info["name"]
    pos = name.index("/")

In between these lines add: name = unquote(name) It should now look like this:

    name = request.match_info["name"]
    name = unquote(name)
    pos = name.index("/")

There is 4 places this text needs to be added in "better_combos.py", and 2 places in "model_info.py".

Save each file when your done and next time you boot up ComfyUI this issue should hopefully be resolved.

Is this caused by a comfy update or sth?

Referring to some other discussion, it is caused by comfy update.

Doing this does indeed "fix" the issue... technically...... however this seems to change the model's file format if you do so._ I followed the steps exactly, and it results in model file formats all being changed to ".sha256" for whatever reason?

EDIT: Okay after restarting the program suddenly it works? Bruh... no idea why it was giving me an error about the format being wrong, which I sadly didnt keep track of what it has said, but it led me to believe it was due to the file format changing. But it would seem that it actually just created a new file, not replacing the file, my mistake.

[CloudWalker-II]

Glad it helped, not sure what exactly happened in your case but I know that whenever you use the lora loader or the checkpoint loader to check the info for a file it will generate a .sha256 file with the same name as the lora / checkpoint in the same folder. I'm guessing this is a file that these custom nodes use to store extra information in.

Just confirming this worked for me too. Thank you.
