TypeError: non-default argument 'text' follows default argument

[Mrguanglei]

Thank you very much for your open source spirit, I got the following error when trying the command "docker run -p 8330:8330 manus-sandbox"

(manus) ubuntu@ubuntu:/datadeep/deep/guanglei/manus/opt/.manus/.sandbox-runtime$ docker run -p 8330:8330 manus-sandbox

@DataClass(frozen=False)
class DOMTextNode(DOMBaseNode):
# 确保非默认参数在最前面
text: str
type: str = 'TEXT_NODE'

def has_parent_with_highlight_index(self) -> bool:
    current = self.parent
    while current is not None:
        # stop if the element has a highlight index (will be handled separately)
        if current.highlight_index is not None:
            return True

I believe it was fixed here:

@dataclass(frozen=False)
class DOMTextNode(DOMBaseNode):
    # Fix: Use field() with default_factory to avoid non-default argument following default argument
    text: str = field(default="")  # Give text a default value
    type: str = 'TEXT_NODE'

Try updating with git pull and running again. I just tested it and it was working fine:

Thank you very much. I also solved this problem by using "@DataClass(frozen=False,init=False)". Now, after I run it successfully, Why does web(http://localhost:8330/) show {"detail":"Not Found"}

[Mrguanglei]

And how can I use it like manus，
