Failure to run app after upgrading to polymer: ^1.0.0-rc.10 and reflectable: ^0.5.0

Question

I just upgraded to polymer: ^1.0.0-rc.10 with a dependecy_overrides of reflectable ^0.5.0.

I observed that whenever I upgraded a project with the above polymer and reflectable I get the following line in the output

Error on line 1, column 1 of https://pub.dartlang.org/api/packages/initialize: Invalid description: "test_package" is a relative path, but this isn't a local pubspec.

Attempting to run my application fails with the following error

"P:\Program Files\Dart\dev\dart-sdk\bin\pub.bat" serve web --port=56435

Run pub cache repair but error remains.

Any suggestion as to how best to correct the issue please.

EDIT 1

I have narrowed down the problem to be caused by either web_component, reflectable or polymer.

I created a new polymer-app with stage-hand and the application runs.

The new polymer-app pubspec.yaml is shown below:

name: 'ui_tester'
version: 0.0.1
description: A web app built using polymer.dart.
#author: Your Name <[email protected]>
#homepage: https://www.example.com

environment:
  sdk: '>=1.9.0 <2.0.0'

dependencies:
  browser: ^0.10.0
  polymer_elements: ^1.0.0-rc.1
  polymer: ^1.0.0-rc.10
  reflectable: ^0.5.0
#  polymer: ^1.0.0-rc.9
#  reflectable: ^0.4.0
  web_components: ^0.12.1

transformers:
- web_components:
    entry_points: web/index.html
- reflectable:
    entry_points: web/index.bootstrap.initialize.dart
- $dart2js:
    $include: '**/*.bootstrap.initialize.dart'
    minify: true
    commandLineOptions:
    - --trust-type-annotations
    - --trust-primitives

As soon as I change the dependencies to reflectable: 0.5.0 and polymer: ^1.0.0-rc.10 from 0.40 and 1.0.0.rc9 (commented lines) respectively the problem is reproduced consistently.

I am suggesting that there might a bug here.

I also noticed that stage-hand now uses

transformers:
- reflectable:
    entry_points: web/index.bootstrap.initialize.dart

instead of

transformers:
- reflectable:
    entry_points: web/index.dart

Are the codes similar in what they do?

Cheers

update

Current workaround - delete .pub directory - run pub upgrade (error message still shown) - limit the analyzer to version 0.27.1 (no 0.26.x or 0.27.1+1 versions)

I'm not sure if it's a pub issue as well because it's about a dev_dependency. I created issue https://github.com/dart-lang/initialize/issues/43 in the initialize package to fix the pubspec.yaml.
