MessageMissingError when using predicates as macros and uuid_v3 or uuid_v5

[mzdemezer]

Describe the bug

We have run into the same issue as #230, but with uuid_v3? and uuid_v5? this time.

To Reproduce

We have run into the bug with code similar to the following one:

require 'dry/schema'

class ExampleService
  include ::Dry::Monads[:do, :result]

  CONTRACT =
    Dry::Schema.Params do
      optional(:filters).hash do
        optional(:id).filled { uuid_v3? | uuid_v4? | uuid_v5? }
        # ...
      end
    end

  private_constant :SCHEMA

  def call(**input)
    valid_data = yield validate(input)
    process(input)
  end

  def validate(input)
    result = CONTRACT.call(input)
    if result.success?
      Success(result.to_h)
    else
      Failure(:invalid_params)
    end
  end

  def process(input)
    # ...
  end
end

upon a call with id in some non-uuid format. The following error message was produced:

API error: Message template for :id under "filters" was not found. Searched in:
"en.dry_schema.errors.rules.id.uuid_v3?.arg.default"
"en.dry_schema.errors.rules.id.uuid_v3?"
"en.dry_schema.errors.uuid_v3?.failure"
"en.dry_schema.errors.uuid_v3?.value.id"
"en.dry_schema.errors.uuid_v3?.value.string.arg.default"
"en.dry_schema.errors.uuid_v3?.value.string"
"en.dry_schema.errors.uuid_v3?.arg.default"
"en.dry_schema.errors.uuid_v3?"

Expected behavior

Proper error message is produced, no exception thrown.

Looking at possible predicates vs the default error messages, how about adding the default messages for v1, v2, v4 and v5?

My environment

• Affects my production application: YES
• Ruby version: 3.1.2
• OS: Linux

Thanks for raising this, @mzdemezer. Looks to me like the fix here will be to follow the same approach as #244, this time focusing on the other UUID versions and getting proper error messaging support across the board.

Would you like to have a go at it?
