Cannot access clipboard in Heroku (Selenium webscraper - python)

Question

I have deployed a very basic webscraper in heroku to periodically press a button, which then copies a link to the browsers clipboard, which I then store in a variable using:

text = pyclip.paste()

This works fine on my local machine that's running windows 10, however when I deploy it to heroku I get the following error:

2021-08-17T12:57:38.512015+00:00 app[worker.1]: text = pyclip.paste()
2021-08-17T12:57:38.512026+00:00 app[worker.1]: File "/app/.heroku/python/lib/python3.9/site-packages/pyclip/__init__.py", line

I am guessing that the dyno dosen't really have a clipboard in place, to which the webdriver can then send the link, and from which pyclip can then retrive it.

Does anyone know a workaround to this or how to setup and access a clipboard when deploying the scraper?

Edit 1 I also installed the heroku-community/apt buildpack and then included copyq in the Aptfile to attempt to setup a clipboard while building the app, but to no avail. Does anyone think Docker is a good idea?

Answer 1

okay as a workaround you could pass ctrl + v, if you are using Selenium and have web elements.

pyperclip.copy("some text")
time.sleep(2)
driver.find_element_by_xpath('some xpath').send_keys(Keys.CONTROL + "v")
