Common validation failures
If validation fails, you can usually fix the dataset and retry quickly. This page covers the most common failure reasons and what to change before your next run.
Format mismatch
Confirm the file uses a supported format and structure from Dataset Format, then re-upload.
Missing required fields
Add the required input/output structure and make sure each record is complete.
Plan size limit exceeded
Reduce dataset size, split data into a smaller run, or choose a plan with more headroom.
Per-line or total-size limits exceeded
Shorten oversized entries and remove malformed rows before retrying.
