Swagger-codegen version

2.2.3-SNAPSHOT

[todrules]

I'm getting the exact same error.

Typescript: 2.1.4
Swagger CodeGen: 2.3.0 (built it a week ago)
@angular: 2.3.0

I'm also using awesome-typescrpit-loader 3.0.0-beta.13. I've had a few problems with that loader lately so thought I'd mention it.

@todrules is it correct to say that it was working fine before? or it never work for you?

[todrules]

It was working on another project I was working on. And while troubleshooting just now, I rolled back Typescript from 2.1.4 to 2.1.1, and it's working. So, something is getting introduced in the newest version of TS that is causing this issue, but at least there's a workaround for now.

[wing328]

@todrules thanks for helping us to pinpoint the issue to Typescript version update. We'll need a fix to be compatible with the latest version as well as old version (e.g. 2.1.1) of TS.

@todrules #4562 has been merged into master. Please pull the latest to give it a try. I believe it should address the issue that you reported if I'm not mistaken.
