## cl.global.1 ohos.i18n Change in the Error Thrown When Parameter Type Verification Failed

**Reason for Change**

Error code 401 is a common error code for parameter type check. The original error code 890001 is no longer thrown in the parameter type check scenario.

**Change Impact**

This change is a non-compatible change.

Before change: If the parameter type is incorrect, the error code 890001 is thrown.

After change: If the parameter type is incorrect, the error code 401 is thrown.

After the change, you need to capture the new error code for error handling.
Currently, the IDE implements parameter type check in the compilation phase. If the IDE is used for compilation, there is no impact.
