Gradio SDK 5.31.0 fully dysfunctional API on Huggingface

xtraa · May 30, 2025, 3:29am

Hi, it seems there is a massive problem with gradio and huggy:

Tested, fixed and not working:
API endpoint diagnostics - tested various URLs
Gradio versions synchronized - version conflicts found
Code bugs fixed - detailed undefined, headers undefined
FastAPI vs. Gradio separated - mount conflicts resolved
Gradio client tested - space-to-space communication
React integration - various API formats
Finally: HuggingFace infrastructure issue identified

results
All Gradio APIs are listed below:

/api/predict → 404
/queue/join → 405
Gradio Client → 405
Space-to-Space → 404

I know Gradio can be a diva, but this is something that we should definitely have a look at. What am I doing wrong? problem is, when I try to use a stable gradio like 4.44 or 5.8 in requirements.txt, the HF environment always sets it back to the bug machine 5.31.0

Hmm… I think it’s just a bug. It doesn’t seem to have been reported as an issue, though.

There’s also a bug in the ImageEditor component in 5.31.0, so I reverted back to 5.29.1…

### Describe the bug @aliabid94 I wanted to address the issue regarding the re…cent changes made to **Fix root on gradio mounted apps setup**, which had been running smoothly for over a year with **FastAPI** and **HAProxy**. After reviewing the situation, I’ve decided to revert the recent comment/adjustment, as it seems to have impacted the previously stable configuration. The setup was operating without any issues, so I believe reverting back to the original configuration will restore the expected behavior. ### Have you searched existing issues? 🔎 - [x] I have searched and found no existing issues ### Reproduction ``` python import gradio as gr def greet(name): return "Hello " + name + "!" with gr.Blocks() as demo: name = gr.Textbox(label="Name") output = gr.Textbox(label="Output Box") greet_btn = gr.Button("Greet") greet_btn.click(fn=greet, inputs=name, outputs=output, api_name="greet") from fastapi import FastAPI app = FastAPI() gr.mount_gradio_app(app, demo, path="/gradio") # run app import uvicorn uvicorn.run(app, host="0.0.0.0", port=8060, root_path='/myapp') ``` ``` bash INFO: Loading environment from '.env' INFO: Started server process [29254] INFO: Waiting for application startup.

`gr.api()` does not work for iterable types are not fully specified

bug

### Describe the bug It seems that `gr.api()` doesn't work if type hints are no…t fully specified in the function. The failure is quite bad with a very long stack trace that doesn't really identify the underlying issue. E.g. test with: ```py import gradio as gr from typing import Any with gr.Blocks() as demo: def log(project: str, run: str, metrics: dict) -> str: pass gr.api(fn=log, api_name="log") demo.launch() ``` This fails because `dict` needs to be `dict[str, Any]`. ### Have you searched existing issues? 🔎 - [x] I have searched and found no existing issues ### Reproduction See above ### Screenshot _No response_ ### Logs ```shell ``` ### System Info ```shell 5.29 ``` ### Severity I can work around it

Thank you for clarification. Problem 2, the FastAPI + Gradio Mount Bug in 5.31.0 hits my problem like Okay that’s bad for now but stuff happens and at least I know now that I’m not missing something. Thank you for your helpful resonse! I’ll keep everyone updated in case I find a way to work around it.
