java - Edge webdriver fails on simple findElement -

i'm using selenium java & testng year testing web application being build dynamically. i'm testing chrome, ff , ie11 , feeling ready start edge webdriver. after implementing edge driver fits os build (release 14393), , loaded web page successfully,

i got issue when trying find element using xpath string:

".//*[contains(@class,'cbola-layer in-content-container-wrapper')]" 

the error:

org.openqa.selenium.nosuchelementexception: no such element

that's simple code i'm using:

string layertypeattribute = driver.findelement(by.xpath(consts.xpath_string)).getattribute("layer_attribute"); 

is there workaround finding xpath?

installed java version 1.8.0_73

update: test fail when trying find element regardless of xpath. tried find class name , id , nothing came up. maybe important i'm testing web application being built async script runs inside page. can find simple html on page not related application, can't find application , not static script tag manually put in page.

screenshot of web elements

try implement explicit wait. driver doesn't stop until element visible. can change 30 seconds amount wish.

webelement layertypeattribute = (new webdriverwait(driver, 30)).until(expectedconditions.presenceofelementlocated(by.xpath("xpath value"))); 

hope answers question.
