selenium and protractor crash, cannot take screenshot

Every test description I have in Jasmine, comes with a afterEach() that checks if the testcase passed. If it did NOT pass, I want to take a screenshot of the offending test screen.

Sometimes I get an error with a crash report. I am unsure how to debug or fix it to learn more.

    afterEach(function() {
        var passed = jasmine.getEnv().currentSpec.results().passed();
        if (!passed) {
            takeScreenCap("FAILEDTESTCASE_" + jasmine.getEnv().currentSpec.description);
        }
    });

The crash itself

I would not reinvent the wheel and use:

It would provide you a nice HTML report with screenshots included. If you want to make the screenshots on failures, set use captureOnlyFailedSpecs to true:

jasmine.getEnv().addReporter(new HtmlScreenshotReporter({
   captureOnlyFailedSpecs: true
}));
