AttributeMetadata symbols import problem

[piotrmrozit]

Hi,

I have a problem with import symbols to AttributeMetadata after update to version 8.2.1:
I try:

1: import {AttributeMetadata} from 'angular2-jsonapi/esm2015/constants/symbols';

give me error:
"TS7016: Could not find a declaration file for module 'angular2-jsonapi/esm2015/constants/symbols'..."

2: import {AttributeMetadata} from 'angular2-jsonapi/constants/symbols';

give me error in angular 8 compile
"Module not found: Error: Can't resolve 'angular2-jsonapi/constants/symbols'"

In version 8.2.1, angular2-jsonapi no folder "dist"...
How do I import symbols? Did anyone have a similar problem.
