Why instapy cannot find element xpath

Question

I executed this code for a testing robot and I got this error and I don't know what i have to do?

from instapy import InstaPy

session = InstaPy(username="<your_username>", password="<your_password>")
session.login()
session.like_by_tags(["bmw", "mercedes"], amount=5)
session.set_dont_like(["naked", "nsfw"])
session.set_do_follow(True, percentage=50)
session.set_do_comment(True, percentage=50)
session.set_comments(["Nice!", "Sweet!", "Beautiful :heart_eyes:"])
session.end()

Error:

Your main issue is the incompatibility between the version of the binaries you are using as follows:

You are using chromedriver=2.44
Release Notes of chromedriver=2.44 clearly mentions the following :

Supports Chrome v69-71

You are using chrome=87.0.4280.66
Release Notes of ChromeDriver v87.0 clearly mentions the following :

Supports Chrome version 87

So there is a clear mismatch between ChromeDriver v2.44 and the Chrome Browser v85.0

Solution

Ensure that:

Selenium is upgraded to current released Version 3.141.59.
ChromeDriver is updated to current ChromeDriver v87.0 level.
Chrome is updated to current Chrome Version 87.0 level. (as per ChromeDriver v87.0 release notes).
If your base Web Client version is too old, then uninstall it and install a recent GA and released version of Web Client.
Take a System Reboot.
Execute your @Test as non-root user.
Always invoke driver.quit() within tearDown(){} method to close & destroy the WebDriver and Web Client instances gracefully.
