Chrome browser's headless option fails to find element

[subhan...@gmail.com]

I have script to visit URL and submit password by searching field by name.

This works fine in normal mode but if I try using headless option this script cannot find the element.

I am doing this.

browser = Browser('chrome', headless=True)
# Visit URL
browser.visit(url)

browser.fill('pass', '{0}'.format(pswd))
browser.find_by_xpath('//*[@id="query"]/table/tbody/tr[3]/td[2]/input').first.click()

The exception I get is below:

Traceback (most recent call last):

    deprv.get_list_NS_cpcodes(cpcodes)

    self.find_by, self.query

splinter.exceptions.ElementDoesNotExist: no elements could be found with name "pass"

I have tried increasing wait time by using time.sleep and "wait_time" but that doesn't help.

Any help is appreciated.

Thanks
