how to fix ?

downgrade

If you can downgrade, downgrade httpx from 0.27.0 to 0.23.3 can fix the problem.Ref: AUTOMATIC1111/stable-diffusion-webui#10149

But this downgrade sometimes casue dependency conflicts. for example:

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
camel-ai 0.2.38 requires httpx<1.0.0dev,>=0.28.0, but you have httpx 0.23.3 which is incompatible.

modify httpx code

  1. open lib/python3.12/site-packages/httpx/_urlparse.py
  2. find urlparse function and modify
def urlparse(url: str = "", **kwargs: str | None) -> ParseResult:
    url = url.replace("::", ":").replace("[", "").replace("]", "") # add this line
    # Initial basic checks on allowable URLs.
    # ---------------------------------------

    # Hard limit the maximum allowable URL length.
    if len(url) > MAX_URL_LENGTH:
        raise InvalidURL("URL too long")

Add the 2th line can fix this problem

url = url.replace("::", ":").replace("[", "").replace("]", "")
