A source map is a guide that helps third-party services–like Noibu–navigate through the labyrinth of transformed and minified code to the original source code. If you opt to use a private source map, you must manually upload the map. Uploading the map in one place will affect any issue with stackframes that follow script paths addressed by the source map.

Your source map may become invalid over time due to regular updates that may affect script paths. We recommend uploading a new source map after every release.

1. Select an issue from the All Issues table and open its Technical Details tab to view the issue's Stacktrace.

2. Click Upload Source Map.
   
   
   
   
3. Select a MAP file from your local documents. Once the sourcemap uploads any affected stackframes should update to Unminified.
