Clearing the trace stack trace

Question:

Is it possible to clear the stack trace and leave only the corresponding frames, excluding everything Protractor, WebDriverJSand Jasminespecific ones?

History:

Let run this test example:

describe("SO test", function () {
    beforeEach(function () {
        browser.get("https://angularjs.org");
    });

    it("should throw a meaningful error", function () {
        element(by.id("not_found")).click();
    });
});

The following command failed to execute:

SO test should throw a meaningful error
  - Failed: No element found using locator: By.id("not_found")

      at Module.load (module.js:356:32)

As you can see, it is not easy to find on which line in the test an error occurred. It is hidden somewhere inside the stack trace, covered with stack frames Protractor, WebDriverJSand Jasmine. This makes it difficult to debug and develop end-to-end tests.

Desired conclusion:

SO test should throw a meaningful error
  - Failed: No element found using locator: By.id("not_found")
