Selenium TypeError: __init__() takes 2 positional arguments but 3 were given
<pre><code>from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions
driver = webdriver.Firefox()
driver.get("http://somelink.com/")


WebDriverWait(driver, 10).until(expected_conditions.invisibility_of_element_located(By.XPATH, "//input[@id='message']"))
# Gives me an error:
TypeError: __init__() takes 2 positional arguments but 3 were given
</code></pre>

<p>...</p>

<pre><code># Simply:
expected_conditions.invisibility_of_element_located(By.XPATH, "//input[@id='message']"))
# Gives me the same error.
TypeError: __init__() takes 2 positional arguments but 3 were given
</code></pre>

<p>The error repeats itself whether I use By.XPATH, By.ID or anything else.</p>

<p>Also, find_element works just fine:</p>

<pre><code>el = driver.find_element(By.XPATH, "//input[@id='message']")
print(el) # returns:
[&lt;selenium.webdriver.firefox.webelement.FirefoxWebElement (session="03cfc338-f668-4fcd-b312-8e4a1cfd9f24", element="c7f76445-08b3-4a4c-9d04-90263a1ef80e")&gt;]
</code></pre>

<p>Suggestions appreciated.</p>

<p><strong>Edit:</strong></p>

<p>Extra parentheses () around <code>By.XPATH, "//input[@id='message']"</code> as suggested in the comments solved the problem.</p>

<p>Change this</p>

<pre><code>WebDriverWait(driver, 10).until(expected_conditions.invisibility_of_element_locateââd((By.XPATH, "//input[@id='message']")))
</code></pre>

<p>I have added extra () , hope this should work.</p>
