Rules afterField and beforeField doesn't works

[fnoquiq]

The alterField and beforeField rule doesn't working. Can anyone tell me what I'm doing wrong?

My validator schema

startDate: schema.date({
  format: 'yyyy-MM-dd',
}),
endDate: schema.date(
  {
     format: 'yyyy-MM-dd',
  },
  [rules.afterField('startDate')]
),

Body request

{
  "startDate": "2000-01-30",
  "endDate": "2000-01-01"
}

My model

@column.date()
public startDate: DateTime

@column.date()
public endDate: DateTime

env

"Node": "12.18.2",
"NPM": "6.14.5",
"@adonisjs/core": "^5.0.0-preview-rc",
