title: 1029: Value too long. | API Docs
description: A string exceeds its character limit.
---

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

The string at param is longer than the part allows; the message states the actual and maximum length.

## Troubleshooting

- Inspect details\[].param and shorten the value; limits are counted in characters, not bytes.
