Gradio5 SSR - RuntimeError: Response content longer than Content-Length

yoonniverse commented 1 month ago

Describe the bug

I installed gradio 5 preview to test ssr feature, but encountered "RuntimeError: Response content longer than Content-Length".

Have you searched existing issues? 🔎

[X] I have searched and found no existing issues

Reproduction

pip install gradio --pre

# test.py
import gradio as gr

with gr.Blocks() as demo:
    gr.Dropdown(["apple", "banana"])

demo.launch(ssr_mode=True)

GRADIO_SERVER_NAME=0.0.0.0 python test.py

It runs fine when I set ssr_mode=False.

Hi @yoonniverse can you try again with the latest beta release we just released? It should be version 5.0.0b6

yoonniverse commented 1 month ago

Thanks for the review, but I still have the same issue after upgrading to 5.0.0b6 too.

abidlabs commented 1 month ago

Thanks for checking, can you please share with us more information about your environment, specifically:

What browser are you using?
What version of Python you are running?
What version of Node you are running?

And you are on Linux, right?

I am getting a very similar error with gradio 5.0.1:

... File "/.venv/lib/python3.11/site-packages/h11/_connection.py", line 545, in send_with_data_passthrough writer(event, data_list.append) File "/.venv/lib/python3.11/site-packages/h11/_writers.py", line 65, in call self.send_data(event.data, write) File "/.venv/lib/python3.11/site-packages/h11/_writers.py", line 91, in send_data raise LocalProtocolError("Too much data for declared Content-Length") h11._util.LocalProtocolError: Too much data for declared Content-Length

Any workarounds?
