Improve "Open in Editor" Error for Missing pathMapping
1 Describe the bug
2 When using the "Open in Editor" feature, if a file's URL from the DevTools doesn't map to a local file due to a
missing or incorrect pathMapping configuration in launch.json, the error message is generic. It doesn't guide
the user on how to resolve the issue.

7 2. Launch the debugger and open the Edge DevTools.
8 3. In the DevTools "Elements" or "Sources" panel, click a link to a source file.
9 4. See the error message.

launch.json.

when using the "Open in Editor" feature.
