It should work as described in the documentation, and there are no issues reported regarding the documentation. It may just be a bug. @meganariley

> \*\*Subject: Application Not Starting - "The main module file does not exist" Despite File Presence\*\*
> 
> Hello,
> 
> I'm experiencing a critical issue with my Streamlit Cloud application that fails to start properly.
> 
> \*\*Problem Description:\*\*
> \- Application URL: \[your-streamlit-app-URL\]
> \- Error message: "The main module file does not exist: /mount/src/mja-poc-oc-p9/app.py"
> \- The app.py file definitely exists at the root of my GitHub repository and is correctly configured
> \- I've verified the project structure, all necessary files are present
> \- I've attempted multiple restarts/redeployments without success
> 
> \*\*Technical Details:\*\*
> \- GitHub Repository: \[your-repo-URL\]
> \- Project structure: app.py is present at the root, with models/ and utils/ folders correctly configured
> \- Logs show that Streamlit cannot find the app.py file although it's visible in GitHub
> \- I'm using Python 3.x with TensorFlow/Keras to load an ML model from Hugging Face
> 
> \*\*What I've Already Tried:\*\*
> \- Restarting the application from the dashboard
> \- Forcing redeployment via minor commits
> \- Checking all configuration parameters
> \- Using optimized code to load the model with TFSMLayer
> 
> \*\*Suspicions:\*\*
> There seems to be a synchronization issue between GitHub and Streamlit Cloud, or a caching problem preventing Streamlit from finding my app.py file.
> 
> Could you please help me resolve this issue so my application can start properly?
> FYI : My app is working well locally in my VM Linux
> Thank you in advance,

> The streamlit iframe embedding in the \[Embed Streamlit Spa…ces on other webpages\](https://huggingface.co/docs/hub/spaces-sdks-streamlit#embed-streamlit-spaces-on-other-webpages) section points to a not maintained space. The displayed iframe keeps displaying streamlits \`Please wait ...\` message.

> \*\*Describe the expected behaviour\*\*
> Should just display a working streamlit space.
> 
> \*\*Additional context\*\*
> I will open a PR to fix this.
