Here's a quick look at our latest product updates.

# Platform bug fixes: Improved error handling and file processing

We've resolved several issues to improve scenario reliability and provide clearer error information.

- **Modules:** An issue has been resolved where modules that process files could fail if the source service did not provide a filename. Scenarios will now handle these cases more gracefully instead of stopping with an error.
- **Error Handling:** Error messages for "404 Not Found" responses in modules have been improved to provide more specific and helpful details, making it easier to diagnose issues with external services.

# Plain-text editing for mapped values and functions

Plain-text editing lets you edit mapped values and functions directly in scenario fields. Update formulas without rebuilding each mapping piece by piece.

### What's new

- **Direct text editing:** Double-click a mapped value or function to switch it to editable text.
- **Formula updates:** Edit values, functions, and keywords directly in the field.
- **Copy and paste:** Copy mapped data or formulas between fields, then adjust the parts you need.
- **Return to mapped format:** Press Esc or click outside the field to return to the normal mapped format.

### Availability

Available for all users in Make.
