Strange Failure issue in Protractor:Jasmine test cases?

UPDATED THE QUESTION ON 17th Sep 2018 Update in Emphasised text

When my test case passes I have no issues in the output screen. It says passed. But when it fails I get this long red output which I am pretty sure is not just about the failure something is wrong in the setup. I am learning automation. Advise me on this. Sharing Info below.

What does this error message imply from the code. Thanks

app.po.ts

import { browser, by, element } from 'protractor';
  export class TestEngine {
  navigateTo() {
    return browser.get('/');
  }

  getParagraphText() {
    return expect(element(by.tagName('p')).getText())
  }
}

testspec.ts

import { TestEngine } from './app.po';

describe('My Test Engine App', () => {
  let page: TestEngine;

  beforeEach(() => {
    page = new TestEngine();
  });

  it('should display display MyTestEngine', () => {
    page.navigateTo();
    expect (page.getParagraphText()).toBeFalsy();

    });
});

EDIT-1 Updating Error message: As you can see here the test cases are passed but I get these errors still at initial stage yet they run . I am working behind a proxy . Is it having something to do with it?

The long error occurs in an erroneous expect(...).

You're trying to do this:

it('should display display MyEngine', () => {
    page.navigateTo();
    expect(expect(element(by.tagName('p')).getText())).toBeFalsy(); 
    // It looks strange because the method getParagraphText does not
    // return a string, it returns an "expect call"
});

To fix your error you should only return the text of the paragraph:

getParagraphText() {
    return element(by.tagName('p')).getText();
}

it('should display display MyEngine', () => {
    page.navigateTo();
    expect(page.getParagraphText()).toEqual('Want to validate an engine?'); 
});

The return type of getParagraphText is Promise<string>. So you're expecting that Promise<string> is equal to your string 'Want to validate an engine?'.

As workaround you can do something like this:

page.getParagraphText().then((text) => {
    expect(text).toEqual('Want to validate an engine?');
});
