I am getting null pointer exception when I try to run JavascriptExecutor. Please find my code below. I have followed the following links from stackoverflow

public void CallApi() {
		try {

			String result = null;
			Thread.sleep(d);
			JavascriptExecutor executor = (JavascriptExecutor) driver;
			String r1 = Uuid(result);
			System.out.println(r1);
			String value = (String) (executor.executeScript("return ContentAPI.getReport('" + r1
					+ "').registerOutputType('dataset', function(data) { console.log(data) });"));
			System.out.println(value);
			String js = "function DrillDown() { ContentAPI.getReport('" + r1
					+ "').drill('Agency Type', 'Online')}; return DrillDown()";
			long value1 = (long) (executor.executeScript(js));

			System.out.println(value1);

		} catch (InterruptedException e) {

			e.printStackTrace();
		}

Please find the error below

enter image description here

when I change the value to as per the following I get null returned

String value1 = (String) (executor.executeScript(js));

  • is the JS snippet in question pure or does it need any dependent js files like Jquery or something? Commented Jun 9, 2019 at 17:34
  • String js = "function DrillDown() { ContentAPI.getReport('" + r1 + "').drill('Agency Type', 'Online')}; return DrillDown()"; don't see any return value in this line. Commented Jun 9, 2019 at 18:49
  • there is no dependent jquery Commented Jun 9, 2019 at 23:54
