## cl.account_os_account.2 Change of the Error Codes in addCredential()

**Change Impact**

For the applications developed based on earlier versions, you need to change the error code processing logic.

**Key API/Component Changes**

Involved API:

```js
  class UserIdentityManager {
    ...
    addCredential(credentialInfo: CredentialInfo, callback: IIdmCallback): void;
    ...
  }
```

Error code list:
| ID| Error Message                    |
| -------- | ------------------- |
| 12300001 | System service exception. |
| 12300002 | Invalid credentialInfo, i.e. authType or authSubType. |
| 12300101 | Token is invalid. |
| 12300106 | Unsupported authType. |
| 12300109 | Operation is canceled. |
| 12300111 | Operation timeout. |
| 12300115 | The number of credentials reaches the upper limit. |


Before change:
The error code 12300002 is returned when a session times out.

After change:
The error code 12300001 is returned when a session times out.


**Adaptation Guide**

Modify the error code processing logic based on the new error codes.
