Double click failed with org.openqa.selenium.WebDriverException: unknown error: failed to parse value of getElementRegion

Question

I want to double click on an element hence have following code -

Actions builder=new Actions(driver);
builder.doubleClick(visibleElement).perform();

But for double click, it results into -

org.openqa.selenium.WebDriverException: unknown error: failed to parse value of getElementRegion

I googled it a lot but did not get what is cause of this and how to resolve this. Could you please help with this?

Answer 1

This error message...

org.openqa.selenium.WebDriverException: unknown error: failed to parse value of getElementRegion

...implies that the GetElementRegion() method failed to parse the value.

Deep dive

This error is coming from element_util.cc:

Status GetElementRegion(
    Session* session,
    WebView* web_view,
    const std::string& element_id,
    WebRect* rect) {
  Status status = CheckElement(element_id);
  if (status.IsError())
    return status;
  base::ListValue args;
  args.Append(CreateElement(element_id));
  std::unique_ptr<base::Value> result;
  status = web_view->CallFunction(
      session->GetCurrentFrameId(), kGetElementRegionScript, args, &result);
  if (status.IsError())
    return status;
  if (!ParseFromValue(result.get(), rect)) {
    return Status(kUnknownError,
          "failed to parse value of getElementRegion");
  }
  return Status(kOk);
}

Reasons and Solutions

There can be diverse reasons and solutions to this error as follows:

• Ensure the Locator Strategy for visibleElement identifies the element uniquely within the DOM Tree

• Induce WebDriverWait for the elementToBeClickable() before you invoke doubleClick() as follows:

  new Actions(driver).doubleClick(new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(visibleElement))).perform();
  

• Add the build() step:

  new Actions(driver).doubleClick(new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(visibleElement))).build().perform();
  

• Before you try to invoke doubleClick() from Actions Class ensure that Selenium have the focus within the correct Frame i.e. either the Top Level View or an <iframe> element.

• Ensure that the element is not within any #shadow-root or shadow-dom.
