I have a user linked to Account. When creating a new user, if a password is entered but is the wrong format, an error message pops up and the correct format password can be entered. But, if initially the page is saved with NO password, then a system error has occured message appears. The log has this error An error has occurred while handling the request.

java.base/java.lang.Thread.run(Thread.java:834) Once something is added to the password field so that the correct error is shown (length, caps, numbers etc) then subsequent blank password fields show the correct message. I guess this is a bug in the underlying code. Is a workaround to add a microflow specifically to check for empty password field and put up a message?
