Error in the second authentication factor

An incorrect OTP code is supplied after a successful password/check with a otp/check REST call.

HTTP Request - /public/authentication/otp/check/

POST https://iam-host.com/auth/rest/public/authentication/otp/check
{
    "otp": "123456"
}

The response is a HTTP 400 BAD REQUEST response and the code returns "OTP_WRONG" to inidicate the reason for the failure.

Since this call returned an error, a "temporaryLockExpiry" is returned as well.
