Phoenix currently surfaces only a generic error message for CSV upload failures in the dashboard, making it hard to debug the root cause. There is an open issue to improve error messaging for CSV uploads, but as of now, the UI does not provide detailed error context for failed dataset creation from CSV files. You may need to check the CSV file for formatting issues or try uploading a minimal version to isolate the problem. For more details, see <https://github.com/Arize-ai/phoenix/issues/7277|GitHub issue #7277>.
Would you like more detail on possible CSV formatting pitfalls or backend debugging steps?
