File upload error when a substate is used

[rushenpatel]

Describe the bug Issue when testing out the file upload utility. The given example works fine out of the box (if my State class inherits directly from pc.State) but if a base state is used an error is thrown on the FE.

To Reproduce Steps to reproduce the behavior:

import pynecone as pc


class State(pc.State):
    """The base state."""


class IndexState(State):
    """The app state."""

    # The image to show.
    img: str

    async def handle_upload(self, file: pc.UploadFile):
        """Handle the upload of a file.

        Args:
            file: The uploaded file.
        """
        upload_data = await file.read()
        outfile = f".web/public/{file.filename}"

        # Save the file.
        with open(outfile, "wb") as file_object:
            file_object.write(upload_data)

        # Update the img var.
        self.img = file.filename


def index():
    """The main view."""
    return pc.vstack(
        pc.upload(
            pc.button("Select File"),
            pc.text("Drag and drop files here or click to select files"),
            border="1px dotted black",
            padding="20em",
        ),
        pc.button(
            "Upload",
            on_click=lambda: IndexState.handle_upload(pc.upload_files())
        ),
        pc.image(src=IndexState.img),
    )


# Add state and page to the app.
app = pc.App(state=State)
app.add_page(index, title="Upload")
app.compile()

Expected behavior File uploads as when state class inherits from pc.State.
