IE Stability issue - WebDriverError

[AliZuhair-AI]

Node version: 7.4.0
Protractor version: 5.1.1
Operating system: Windows 7
Browser: Internet Explorer 11

I recently upgraded to Protractor 5.1.1 and started to seeing this error show up occasionally:

WebDriverError: JavaScript error (WARNING: The server did not provide any stacktrace information)
Command duration or timeout: 49 milliseconds

It seems to be coming from the following code under *\lib\browser.ts

return this.driver.wait(() => {
            return this.executeScriptWithDescription('return window.location.href;', msg('get url'))
                .then(
                    (url: any) => {
                      return url !== this.resetUrl;
                    },
                    (err: IError) => {
                      if (err.code == 13 || err.name === 'JavascriptError') {
                        // Ignore the error, and continue trying. This is
                        // because IE driver sometimes (~1%) will throw an
                        // unknown error from this execution. See
                        // https://github.com/angular/protractor/issues/841
                        // This shouldn't mask errors because it will fail
                        // with the timeout anyway.
                        return false;
                      } else {
                        throw err;
                      }
                    });

If I change the the line above from

if (err.code == 13 || err.name === 'JavascriptError')

to

if (err.code == 13 || err.name === 'JavascriptError' || err.name === WebDriverError)

then the problem goes away.

I reported this issue previously and it was closed with a reference to 4149. However, that reference is to a different issue.

I can confirm the findings of OP.

@AliZuhair-AI Are you using Selenium Server? How does Protractor connect to IE?

[AliZuhair-AI]

@thorn0 I am using BrowserStack, which uses InternetExplorerDriver

@thorn0 You need do download and configure IE server file to connect it locally

For running IE locally we need to have following binary in the path

I have the same issues as OP. The first IE test fails in approximately every second test run.
The changes proposed in the first post fix the issues for me locally.
Is somebody still on this?
