Can you please provide some context?

• What feature of Amplify are you using and what is the action that led to the error?
• Please share a code sample

[vc-ishver]

I am using "aws-amplify": "^1.2.5-unstable.11" for login purpose in angular 8 universal.

On stable version gives "WINDOW NOT DEFINED" error and I add the unstable version "1.2.5-unstable.5" and on that time it works fine.

But as now, it won't allow me deploy as well as run on local machine with "ng serve".

I'm having the same problem using @aws-cdk

We are facing the same issue in AWS CodeBuild pipeline with Angular universal 8 and "aws-amplify": "^2.1.0"

[vc-ishver]

I had try with "aws-amplify": "^2.1.1-unstable.0" , but it can't work with latest unstable version.

ERROR in ../node_modules/@aws-amplify/core/lib-esm/ServiceWorker/ServiceWorker.d.ts:23:9 - error TS1086: An accessor cannot be declared in an ambient context.

I found out that this error was because last version of aws-cdk (v. 1.16.0) had breaking changes on Stack generation.
Previously we were using v. 1.15.0.

• ### 1.15.0:
  _node_modules/@aws-cdk/core/lib/cfn-element.d.ts_

52    readonly creationStack: string[];

• ### 1.16.3:
  _node_modules/@aws-cdk/core/lib/cfn-element.d.ts_

52     get creationStack(): string[];

This getter (and all new ones in other files) is what is crashing the Stack generation.

[iartemiev]

@vc-ishver Thank you for the additional info. PR with the fix is up. Will update this issue once it's merged

[iartemiev]

This issue was caused by changes to declaration files generated by TypeScript 3.7+, which are incompatible with the versions of TypeScript supported by current versions of Angular Compiler. Building aws-amplify with TypeScript 3.6.4 resolves the issue.

[ekzGuille]

@iartemiev Thank you.
I will check in my project if updating to latest version also updates Typescript to 3.7+ version. If so, I will downgrade to a working version.

[iartemiev]

@vc-ishver @ekzGuille please try the latest unstable version of aws-amplify (2.1.1-unstable.5
or later)
