# Hugging Face Space Deployment Fix

## Issue

The Hugging Face Space deployment is failing with the following error:

```
Traceback (most recent call last):
  File "/home/user/app/app.py", line 8, in <module>
    from pages.dashboard import create_dashboard_page
  File "/home/user/app/pages/dashboard.py", line 8, in <module>
    from utils.state import generate_id, get_timestamp, record_activity
  File "/home/user/app/utils/state.py", line 9, in <module>
    from utils.error_handling import handle_exceptions, ValidationError, safe_get
ImportError: cannot import name 'safe_get' from 'utils.error_handling' (/home/user/app/utils/error_handling.py)
```

## Root Cause Analysis

After investigating the codebase, I've identified the following issues:

1. The `safe_get` function is correctly defined in `utils/error_handling.py` (around line 220-240)
2. The function is also correctly imported in `utils/__init__.py`
3. The error is likely occurring due to one of the following reasons:
   - The deployment environment might be using a different Python version than your local environment <mcreference link="https://discuss.huggingface.co/t/how-to-set-the-python-version-in-hugging-face-space/130390" index="1">1</mcreference>
   - There might be a caching issue in the Hugging Face Space <mcreference link="https://discuss.huggingface.co/t/receiving-this-error-even-with-a-new-space/43285" index="2">2</mcreference>
   - The deployment process might not be correctly installing all dependencies <mcreference link="https://discuss.huggingface.co/t/custom-python-packages-at-spaces/17250" index="4">4</mcreference>

## Solution

Here are the steps to fix the issue:

### 1. Verify the safe_get function in error_handling.py

The `safe_get` function is defined in `utils/error_handling.py` as follows:

```python
def safe_get(data, path, default=None):
    """
    Safely get a value from a nested dictionary.
    
    Args:
        data (dict): The dictionary to get the value from.
        path (str): The path to the value, using dot notation (e.g., "user.profile.name").
        default: The default value to return if the path doesn't exist.
    
    Returns:
        The value at the specified path, or the default value if the path doesn't exist.
    """
    keys = path.split('.')
    result = data
    
    try:
        for key in keys:
            if isinstance(result, dict):
                result = result.get(key, default)
            else:
                return default
        return result
    except Exception:
        return default
```

### 2. Ensure utils/__init__.py correctly imports safe_get

Verify that `utils/__init__.py` includes the `safe_get` function in its imports:

```python
# Mona - AI Productivity Platform
# Utils package initialization

# This file makes the utils directory a Python package
# and allows for easier imports throughout the application

# Import commonly used utilities for easier access
from utils.storage import load_data, save_data
from utils.state import generate_id, get_timestamp, record_activity
from utils.logging import get_logger, setup_logger
from utils.error_handling import handle_exceptions, ValidationError, safe_get

__version__ = "0.1.0"
```

### 3. Add a direct import in state.py

To ensure the import works correctly, you can modify `utils/state.py` to import `safe_get` directly from `error_handling.py` rather than relying on the package import:

```python
# Change this line:
from utils.error_handling import handle_exceptions, ValidationError, safe_get

# To this more explicit import:
from utils.error_handling import handle_exceptions, ValidationError
from utils.error_handling import safe_get  # Explicit import
```

### 4. Add an initialization check in app.py

Add a try-except block at the beginning of `app.py` to catch and provide more detailed information about import errors:

```python
try:
    # Import pages
    from pages.dashboard import create_dashboard_page
    # ... other imports
except ImportError as e:
    import sys
    print(f"CRITICAL IMPORT ERROR: {e}", file=sys.stderr)
    print(f"Python version: {sys.version}", file=sys.stderr)
    print(f"Python path: {sys.path}", file=sys.stderr)
    raise
```

## Hugging Face Space Specific Recommendations

1. **Specify Python Version**: Add the following to your README.md file to ensure a compatible Python version <mcreference link="https://discuss.huggingface.co/t/how-to-set-the-python-version-in-hugging-face-space/130390" index="1">1</mcreference>:
   ```
   python_version: 3.9.13
   ```

2. **Factory Reboot**: After making changes, perform a factory reboot of your Hugging Face Space <mcreference link="https://discuss.huggingface.co/t/receiving-this-error-even-with-a-new-space/43285" index="2">2</mcreference>.

3. **Check Dependencies**: Ensure all dependencies in requirements.txt are correctly specified with proper package versions <mcreference link="https://discuss.huggingface.co/t/custom-python-packages-at-spaces/17250" index="4">4</mcreference>.

4. **Add Fallback Import**: If the issue persists, you can add a fallback import mechanism in `state.py`:

   ```python
   try:
       from utils.error_handling import handle_exceptions, ValidationError, safe_get
   except ImportError:
       # Define safe_get locally as a fallback
       def safe_get(data, path, default=None):
           keys = path.split('.')
           result = data
           try:
               for key in keys:
                   if isinstance(result, dict):
                       result = result.get(key, default)
                   else:
                       return default
               return result
           except Exception:
               return default
       # Still try to import the other functions
       from utils.error_handling import handle_exceptions, ValidationError
   ```

5. **Debugging**: Add more logging statements to help debug deployment issues.

6. **Environment Variables**: If your application uses environment variables, make sure they are properly set in the Hugging Face Space.

7. **File Path Differences**: Be aware that file paths might be different between your local environment and the Hugging Face Space environment. Make sure to use relative imports correctly.
