Source map debugger shows success with no errors
Resolution
If the debugger reports no errors but the stack trace still looks incorrect, Sentry is likely applying the uploaded source maps. In that case the problem is usually the source maps or built artifacts themselves. Sentry does not validate that uploaded maps correctly match your original source code.
Open the event and use the source maps section’s Minified toggle.
If line numbers, file paths, or function names change when you toggle, the maps are being applied.
If the maps apply but the stack is still wrong, check how your build generates maps. Common causes include incorrect intermediate source maps, missing
sourcesContent, or maps that do not match the uploaded JavaScript files.Follow Troubleshooting Source Maps to verify the maps are built correctly.
