In selenium,if element id=“tagName”,then unknown error: a.tagName.toUpperCase is not a function

[SAI VINAY]

A Web element of an Angular JS Web Application in a DOM looks like

 <input id="tagName" class="form-control ng-touched " type="text" _ngcontent-c29="" name="tagName" pattern="^(?!\s*$)[^\/]+" required=""/>

When I try to submit the form through selenium WebDriver containing the above element in a web application we are getting the below error-

 java.lang.AssertionError: unknown error: a.tagName.toUpperCase is not a function

We are facing the same issue even in Selenium2.53 with Firefox and Selenium3.4 with Chrome combinations.

We tried clicking the elements with JavaScript executor also but did not work.

We have tried feeding the element with the below snippets of code. 

WebElement we = driver.findElement(By.id("tagName"));

JavascriptExecutor jse= (JavascriptExecutor) driver; jse.executeScript("arguments[0].value='Hello';", we);

We can see the value is getting entered into the field but the application is not recognizing that the value is entered.It is showing the error as "value is required". When we interpret the automation using breakpoint and enter text manually in the element no error comes.

There is also similar open issue in the below link.https://bugs.chromium.org/p/chromedriver/issues/detail?id=767

Please let us know whether there is any method to get rid of the error without changing the id value of the element in the DOM.

Hi,

Is there any reason why you are using Selenium instead of Protractor for angularJS apps?Selenium is not fully compatible to work with Angular elements..

Its little unclear of what you are trying to do..Are you entering a text to the element and then asserting the value of the text?What is the action your trying to do?

@Thivya

Isnt Protractor meant to be a JavaScript binding ? I believe the OP is trying to work with Java and not JavaScript.

 

 

Thanks & Regards

Protractor is primarily for AngularJS applications..

I'm not able to understand the action being performed.Java/Javascript is fine with me.

Its a web driver issue. try calling other browser or update your driver, then run test again.
