V4.0.3 not working in production build with fesm5 (Cannot read property 'kind' of undefined)

[yellooo]

It works fine when i setting the buildOptimizer to false in the angular.json file.

But when the buildOptimizer it's set on true, i get this error:

ERROR in C:/Front/node_modules/ngx-virtual-scroller/fesm5/ngx-virtual-scroller.js Module build failed (from C:/Front/node_modules/@angular-devkit/build-angular/node_modules/@angular-devkit/build-optimizer/src/build-optimizer/webpack-loader.js): TypeError: Cannot read property 'kind' of undefined at isAngularDecoratorMetadataExpression (C:\Front\node_modules\@angular-devkit\build-angular\node_modules\@angular-devkit\build-optimizer\src\transforms\scrub-file.js:265:35)

I'm on Angular v7.1.1 and ngx-virtual-scroller v4.0.3

"devDependencies": { "@angular-devkit/build-angular": "0.13.10", "@angular-devkit/build-ng-packagr": "0.13.10", "@angular/cli": "7.3.10" }

Thanks for all
