Node: Stack trace is incomplete with async/await

Created on 19 Jan 2018 · 3Comments · Source: nodejs/node

Version : v8.6.0
Platform: MacOS

Protractor version: 5.1.2

configuration:

   exports.config = {
    framework: 'jasmine2',
    jasmineNodeOpts: {
    showColors: true,
    defaultTimeoutInterval: 300000,
    print: function () {
    }
  }
 onPrepare()
  {
    jasmine.getEnv().addReporter(new SpecReporter({spec: {displayStacktrace: true,}}));
  }

Sample spec:

```
it('Protractor stack trace issue', async () =>
{
const helper = new SearchHelper();
await helper.doSearch('test');
});

**search-helper.ts:**

async doSearch(text) { 
  await browser.get('http://google.com'); 
  await browser.wait(EC.visibilityOf(element(by.name('q1'))), 10000, 'No Element found'); 
  await element(by.name('q1')).click(); //invalid locator 
}

**1. Stack Trace with browser.wait**

**2. If we comment browser.wait statement then the stacktrace is**

```

Observe the 2nd stack trace, it has references to search-helper file but it's not there in the first stack trace. It's very important to have this reference in stack trace for debugging.

Tried by increasing Error.stackTraceLimit also but no luck.
