Getting this error while deploying on community cloud - installer returned a non-zero exit code. Error during processing dependencies! Please fix the error and push an update, or try restarting the app.

Hey, thanks for sharing your question and repo link! This is a super common issue—your app works locally but fails on Streamlit Community Cloud. The most frequent causes are: (1) missing or misspelled dependencies in requirements.txt, (2) including standard library modules (like base64 or json) in requirements.txt, or (3) version mismatches between your local and cloud environments.
