Trouble in adding user or Sending mail

Hello,
I'm trying to run your development version using Intellij idea. Normal registration from register button working fine but when I'm trying to ADD user from Admin user It giving me error

Unrecognized field "distanceUnit" (class org.traccar.model.User), not marked as ignorable (21 known properties: "readonly", "limitCommands", "deviceLimit", "name", "latitude", "phone", "admin", "userLimit", "zoom", "twelveHourFormat", "attributes", "deviceReadonly", "token", "id", "email", "longitude", "password", "map", "coordinateFormat", "disabled", "expirationTime"])
 at [Source: org.glassfish.jersey.message.internal.ReaderInterceptorExecutor$UnCloseableInputStream@fa99fb5; line: 1, column: 131] (through reference chain: org.traccar.model.User["distanceUnit"])

Also giving error while I'm trying to test mail.
HTTP 404 Not Found - NotFoundException (...) but I didn't change any files , I just followed your instruction

Most likely your web app doesn't match back-end or there is some problem with database schema.

Is there any solutions that I can follow ?
I did accordingly to your documentation instructions.

You should download stable versions of Traccar if you are not prepared to deal with issues and conflicts.
