how I should resolve this problem?

For anyone who found this issue in 2022, try to to make fields (password, email) not nullable, DO NOT THIS:

 @column()
  public email: string | null

 @column()
 public password: string | null

DO THIS, these field's cannot be nullable in LucidProviderContract

 @column()
  public email: string

 @column()
 public password: string
