Hi @rustic scarab. I'm happy to dig into this for you! I'll check my internal sources for answers to your question! :wave:

If you are seeing the error "A required debug information file was missing" in Unreal Engine 5.6 and cannot see further details in the logs, here are some steps and context based on the knowledge sources:

1. Debug Information Files Are Required
   Sentry needs debug information files (such as PDB for Windows, dSYM for macOS/iOS, ELF for Linux/Android, etc.) to symbolicate crashes and provide detailed stack traces. If these files are missing or not uploaded, Sentry cannot fully process crash reports and will show this error. You must upload these files for all relevant libraries, including dependencies and OS libraries, not just your main application binary. For optimized builds, you may also need to upload the binaries themselves to provide Call Frame Information (CFI) for accurate stack traces Debug Information Files Upload Debug Symbols.

2. Automatic Symbol Upload in Unreal
   The Sentry Unreal SDK can upload debug symbols automatically during build if you enable this in Project Settings > Plugins > Sentry ("Upload debug symbols automatically") or by setting the SENTRY_UPLOAD_SYMBOLS_AUTOMATICALLY environment variable to True. Make sure your organization, project, and auth token are correctly configured in the sentry.properties file or via environment variables Debug Symbols Uploading.

3. Manual Upload and Verification
   You can manually upload debug files using sentry-cli:

sentry-cli --auth-token <TOKEN> debug-files upload --org <ORG> --project <PROJECT> PATH_TO_SYMBOLS

After uploading, it may take up to an hour for Sentry to use the new files for crash processing. Existing events are not reprocessed Uploading Files.

4. Checking Which File Is Missing
   To identify which debug file is missing, go to the Sentry issue in the UI, scroll to "Images Loaded," and look for entries marked as missing. This section provides the file name, path, and debug ID required. If you cannot see this in the logs, the Sentry UI is the best place to get this detail Github Issue Example.

5. Common Pitfalls

• Ensure you are uploading to the correct Sentry project; mismatched project slugs can cause this error even if the files are uploaded Github Issue Example.
• If you are using a symbol server, verify that Sentry can access it and that the required files are present Self-hosted Sentry Issue.

Summary:
The error means Sentry cannot find the debug information file it needs to symbolicate a crash. Check the Sentry UI for details on which file is missing, ensure your debug files are uploaded to the correct project, and verify your upload configuration. If the logs do not show details, the Sentry web interface is the authoritative source for missing file diagnostics.

If you need more specific troubleshooting for log visibility in UE5.6, the knowledge sources do not provide further details. Please check the Sentry UI for the most precise information on missing debug files.
