ng e2e Bug

[pxstrana]

Hello, I´m working on a solid app based on this structure and I´m having some problems with the e2e tests.

In order to try to solve the error I deployed this small app from zero and tried to run the e2e tests, in this case I didn´t create any but I was expecting some error like empty tests or everything passed. But it raised this (you can skip the trace I´ve found the error):

 throw er; // Unhandled 'error' event
      ^

Error: write EPIPE

If you upgrade angular, the error trace will be more verbose. Command : ng update @angular/cli @angular/core.

Now, it will show something like this:

ERROR in src/app/services/solid.auth.service.ts(37,5): error TS2322: Type 'Observable<{}>' is not assignable to type 'Observable<SolidSession>'.
  Type '{}' is missing the following properties from type 'SolidSession': accessToken, clientId, idToken, sessionKey, webId

To make it possible to run the test I just deleted the session type of solid.auth.service.ts

//code without modification
export class AuthService {
  session: Observable<SolidSession>;
  ...

Now you can run the tests, build etc. without any problem.

Interesting! Thank you for the report. Is this something you could open a PR for?

I tried, but I don´t have access to open it. But, anyway it is a small change of one line.
