error during login

Hi.
I’ve a problem during login.
I create a basic user; when i do login in Servoy developer, with this user, all works fine but in application servoy_client, downloaded from Servoy Server, this client got an error:“It seems you did not fill in a required”.

In Servoy server I have find this error in the server log:

“Error executing sql: update sec_user set times_wrong_login=? where
user_id = ? and owner_id in (?, ?) with params: [NullValue with type:
