<@U04UQ68083H> explain reason for this error:
```{
  statusCode: 400,
  message: 'Linked credentials do not match.',
  code: 4010009,
  meta: {}
}```

The error message:  ```json {   "statusCode": 400,   "message": "Linked credentials do not match.",   "code": 4010009,   "meta": {} } ```  means that the credentials you are trying to link do not match the expected credentials for the current account. This typically occurs during account linking or social sign-in flows when the provided credentials (such as an email, password, or social login) do not correspond to the credentials already associated with the account you are attempting to link to. As a result, Ory Kratos returns this error to indicate a mismatch in the linked credentials, preventing the linking operation from proceeding.  You can find this error documented in the Ory Kratos UI messages reference, where it is described as:  &gt; Linked credentials do not match. (4010009)  This is an error type message and is used to signal issues with credential matching during account linking or authentication flows [Linked credentials do not match. (4010009)](<https://www.ory.sh/docs/kratos/concepts/ui-messages#linked-credentials-do-not-match-4010009>).
