+# Runtime Error Fix Summary
+
+## Problem
+The application was failing with a `ModuleNotFoundError: No module named 'controller'` when deployed. This error occurred because Python couldn't locate the `controller` package during the import process in `app.py`.
+
+## Root Cause
+The issue was related to Python's module search path. When the application was deployed, the working directory or Python path didn't include the directory containing the `controller` package, causing the import to fail.
+
+## Fixes Applied
+
+### 1. Updated Dockerfile
+Added `--chdir /app` to the gunicorn command to ensure the working directory is correctly set:
+```dockerfile
+CMD ["gunicorn", "--bind", "0.0.0.0:7860", "--chdir", "/app", "app:app"]
+```
+
+### 2. Updated Procfile
+Added `--chdir /app` to the gunicorn command for Heroku/Render deployments:
+```
+web: gunicorn --bind 0.0.0.0:$PORT --chdir /app app:app
+```
+
+### 3. Updated render.yaml
+Added `--chdir /app` to the startCommand for Render deployments:
+```yaml
+startCommand: "gunicorn --bind 0.0.0.0:$PORT --chdir /app app:app"
+```
+
+### 4. Modified app.py
+Added explicit Python path manipulation at the beginning of the file to ensure the current directory is in the Python path:
+```python
+import sys
+import os
+
+# Add the current directory to Python path
+sys.path.insert(0, os.path.dirname(os.path.abspath(__file__)))
+```
+
+## Why These Fixes Work
+1. The `--chdir` option ensures that gunicorn starts in the correct directory where all the application modules are located.
+2. The Python path modification in `app.py` provides a fallback mechanism to ensure the current directory is always in the Python path, regardless of how the application is started.
+
+These changes should resolve the ModuleNotFoundError and allow the application to start successfully in various deployment environments.
