PSI and index do not match error in RM 2019.3 EAP

I am now getting an error when first launching railways in RM. This doesn't seem to affect anything, but figured that I should put in an issue just in case it does cause a problem further down the road.

Not sure if this is an issue with RM itself or railways.

Thanks!

module AWS
  module Record

    # An ActiveRecord-like interface built ontop of Amazon SimpleDB.
    #
    #     class Book < AWS::Record::Model
    #
    #       string_attr :title
    #       string_attr :author
    #       integer_attr :number_of_pages
    #
    #       timestamps # adds a :created_at and :updated_at pair of timestamps
    #

    #     b.save
    #
    # # Attribute Macros
    #
    # When extending AWS::Record::Model you should first consider what
    # attributes your class should have.  Unlike ActiveRecord, AWS::Record
    # models are not backed by a database table/schema.  You must choose what
    # attributes (and what types) you need.
    #
    # * `string_attr`
    # * `boolean_attr`
    # * `integer_attr`
    # * `float_attr`
    # * `datetime_attr`
    # * `date_attr`
    #
    # ### Usage
    #
    # Normally you just call these methods inside your model class definition:
    #
    #     class Book < AWS::Record::Model
    #       string_attr :title
    #       boolean_attr :has_been_read
    #       integer_attr :number_of_pages
    #       float_attr :weight_in_pounds
    #       datetime_attr :published_at
    #     end
    #
    # For each attribute macro a pair of setter/getter methods are added #
    # to your class (and a few other useful methods).
    #
    #     b = Book.new
    #     b.title = "My Book"
    #     b.has_been_read = true
    #     b.number_of_pages = 1000
    #     b.weight_in_pounds = 1.1
    #     b.published_at = Time.now
    #     b.save
    #
    #     b.id #=> "0aa894ca-8223-4d34-831e-e5134b2bb71c"
    #     b.attributes
    #     #=> { 'title' => 'My Book', 'has_been_read' => true, ... }
    #
    # ### Default Values
    #
    # All attribute macros accept the `:default_value` option.  This sets
    # a value that is populated onto all new instnaces of the class.
    #
    #     class Book < AWS::Record::Model
    #       string_attr :author, :default_value => 'Me'
    #     end
    #
    #     Book.new.author #=> 'Me'
    #
    # ### Multi-Valued (Set) Attributes
    #
    # AWS::Record permits storing multiple values with a single attribute.
    #
    #     class Book < AWS::Record::Model
    #       string_attr :tags, :set => true
    #     end
    #
    #     b = Book.new
    #     b.tags #=> #<Set: {}>
    #
    #     b.tags = ['fiction', 'fantasy']
    #     b.tags #=> #<Set: {'fiction', 'fantasy'}>
    #
    # These multi-valued attributes are treated as sets, not arrays.  This
    # means:
    #
    # * values are unordered
    # * duplicate values are automatically omitted
    #
    # Please consider these limitations when you choose to use the `:set`
    # option with the attribute macros.
    #
    # # Validations
    #
    # It's important to validate models before there are persisted to keep
    # your data clean.  AWS::Record supports most of the ActiveRecord style
    # validators.
    #
    #     class Book < AWS::Record::Model
    #       string_attr :title
    #       validates_presence_of :title
    #     end
    #
    #     b = Book.new
    #     b.valid? #=> false
    #     b.errors.full_messages #=> ['Title may not be blank']
    #
    # Validations are checked before saving a record.  If any of the validators
    # adds an error, the the save will fail.
    #
    # For more information about the available validation methods see
    # {Validations}.
    #
    # # Finder Methods
    #
    # You can find records by their ID.  Each record gets a UUID when it
    # is saved for the first time.  You can use this ID to fetch the record
    # at a latter time:
    #
    #     b = Book["0aa894ca-8223-4d34-831e-e5134b2bb71c"]
    #
    #     b = Book.find("0aa894ca-8223-4d34-831e-e5134b2bb71c")
    #
    # If you try to find a record by ID that has no data an error will
    # be raised.
    #
    # ### All
    #
    # You can enumerate all of your records using `all`.
    #
    #     Book.all.each do |book|
    #       puts book.id
    #     end
    #
    #     Book.find(:all) do |book|
    #       puts book.id
    #     end
    #
    # Be careful when enumerating all.  Depending on the number of records
    # and number of attributes each record has, this can take a while,
    # causing quite a few requests.
    #
    # ### First
    #
    # If you only want a single record, you should use `first`.
    #
    #     b = Book.first
    #
    # ### Modifiers
    #
    # Frequently you do not want ALL records or the very first record.  You
    # can pass options to `find`, `all` and `first`.
    #
    #     my_books = Book.find(:all, :where => 'owner = "Me"')
    #
    #     book = Book.first(:where => { :has_been_read => false })
    #
    # You can pass as find options:
    #
    # * `:where` - Conditions that must be met to be returned
    # * `:order` - The order to sort matched records by
    # * `:limit` - The maximum number of records to return
    #
    # # Scopes
    #
    # More useful than writing query fragments all over the place is to
    # name your most common conditions for reuse.
    #
    #     class Book < AWS::Record::Model
    #
    #       scope :mine, where(:owner => 'Me')
    #
    #       scope :unread, where(:has_been_read => false)
    #
    #       scope :by_popularity, order(:score, :desc)
    #
    #       scope :top_10, by_popularity.limit(10)
    #
    #     end
    #
    #     # The following expression returns 10 books that belong
    #     # to me, that are unread sorted by popularity.
    #     next_good_reads = Book.mine.unread.top_10
    #
    # There are 3 standard scope methods:
    #
    # * `where`
    # * `order`
    # * `limit`
    #
    # ### Conditions (where)
    #
    # Where accepts aruments in a number of forms:
    #
    # 1. As an sql-like fragment. If you need to escape values this form is
    #    not suggested.
    #
    #        Book.where('title = "My Book"')
    #
    # 2. An sql-like fragment, with placeholders.  This escapes quoted
    #    arguments properly to avoid injection.
    #
    #        Book.where('title = ?', 'My Book')
    #
    # 3. A hash of key-value pairs. This is the simplest form, but also the
    #    least flexible.  You can not use this form if you need more complex
    #    expressions that use or.
    #
    #        Book.where(:title => 'My Book')
    #
    # ### Order
    #
    # This orders the records as returned by AWS.  Default ordering is ascending.
    # Pass the value :desc as a second argument to sort in reverse ordering.
    #
    #     Book.order(:title)        # alphabetical ordering
    #     Book.order(:title, :desc) # reverse alphabetical ordering
    #
    # You may only order by a single attribute. If you call order twice in the
    # chain, the last call gets presedence:
    #
    #     Book.order(:title).order(:price)
    #
    # In this example the books will be ordered by :price and the order(:title)
    # is lost.
    #
    # ### Limit
    #
    # Just call `limit` with an integer argument.  This sets the maximum
    # number of records to retrieve:
    #
    #     Book.limit(2)
    #
    # ### Delayed Execution
    #
    # It should be noted that all finds are lazy (except `first`).  This
    # means the value returned is not an array of records, rather a handle
    # to a {Scope} object that will return records when you enumerate over them.
    #
    # This allows you to build an expression without making unecessary requests.
    # In the following example no request is made until the call to
    # each_with_index.
    #
    #     all_books = Books.all
    #     ten_books = all_books.limit(10)
    #
    #     ten_books.each_with_index do |book,n|
    #       puts "#{n + 1} : #{book.title}"
    #     end
    #
