Hi @Madhu_Gn , We observed this issue that when OTP request/Authentication is performed for a UIN before the credential is issued for that, it caches the null salt key and it results in this error. This will get fixed in future release. a workaround for this is not to perform OTP request/authentication before the credential is issued, we can have some wait time. And, if this issue occurred, the service needs to re-started to clear the salt cache. Please refer to the issue on this.
