# Duplicate Client

> A client with this information already exists

## Cause

A client with the provided information already exists and cannot be imported again.

## Fix

Remove the duplicate client from the import or update the existing client instead.

## Retry safety

Not retryable until the underlying state or request changes.

## Raised by

No current operation documents this problem type in the OpenAPI definition. If you receive it in production, treat that as a contract gap and tell us.

## Example

```json theme={null}
{
  "type": "https://docs.guile.app/problems/duplicateClient",
  "title": "Duplicate Client",
  "status": 409,
  "detail": "A client with the provided information already exists and cannot be imported again."
}
