Versions.

@angular/cli: 1.3.1
node: 7.10.1
os: darwin x64

Repro steps.

Following the docs in https://github.com/angular/angular-cli/blob/1.3.x/docs/documentation/stories/universal-rendering.md

I get

/Users/lucaswxp/xxx/site/node_modules/@angular/core/bundles/core.umd.js:501
            var /** @type {?} */ meta = Reflect$1.getOwnMetadata('propMetadata', target.constructor) || {};
                                                  ^

Not sure if it's a angular bug, but I followed all the steps mentioned in the docs. Any help?

[lucaswxp]

Guys, I see this is an actual angular cli bug? Any idea how can I fix it temporarily?

[ruyfortini]

Hello, any updates on this?
I'm about to launch a big project and we need this working.

Appreciate the support.

[ruyfortini]

@hansl appreaciate if you can give us a date estimate for this fix.

@hansl @ruyfortini Is there any temporary way around this bug? Anything at all I can do just to load my site somewhere?

[EmptyPockets]

@hansl @ruyfortini Quick update, I only get this error if I try to include this plugin: https://github.com/mujtaba01/ngx-owl-carousel. I assume that's not related to the bug but is instead a universal thing?

[BlankHrt]

same problem with universal
have you solved yet? @lucaswxp @EmptyPockets

[hlszk]

I get this error message building an universal project without angular-cli, so I guess it is rather a platform-server issue.

I think it is because you are using a dependency that uses methods not supported in node:
http://node.green/#ESNEXT-pre-strawman-Metadata-reflection-API-Reflect-getOwnMetadata

In your case is 'angular2-text-mask'

[alan-agius4]

At server level you need to include a reflect polyfill such as reflect-metadata.

Please take a look at this story https://github.com/angular/angular-cli/wiki/stories-universal-rendering and this starter https://github.com/angular/universal-starter/blob/master/server.ts#L2
