title: 1007: Duplicate value. | API Docs
description: A value that must be unique within the part appears twice.
---

**HTTP status:** `422`. May also be reported as a field-level finding in `error.details[]`.

Two entries in the part carry the same value where uniqueness is required, such as two rows or buttons with the same id. Make each value unique and resend.

## Troubleshooting

- Inspect details\[].param for the second occurrence.
