python – Xpath wrong in selenium

Regarding the tbsCertificate error, add the below line: This will ignore those errors.

options = webdriver.ChromeOptions()
options.add_experimental_option('excludeSwitches', ['enable-logging'])

Coming to your next issue, which is trying to locate the “Keywords” element. Try this Xpath expression:

(//div[@id='research-link']//span)[1]

Code should be:

element = WebDriverWait(driver,30).until(EC.presence_of_element_located((By.XPATH, "(//div[@id='research-link']//span)[1]")))
element.click()

Or:

WebDriverWait(driver,30).until(EC.element_to_be_clickable((By.XPATH, "(//div[@id='research-link']//span)[1]")))
element.click()

You can even try using below XPath expression:
This expression searches all the span nodes which contain text “Keywords”

//span[text()='Keywords']
