Twitter-Bot | Twitter Bot will follow all users | Bot library

I am running a bot that periodically downloads an image from a website and uploads it to Twitter. Sometimes, however, the images get grey bars on the bottom, resulting in uploaded images that look like this or this.

This is the code that downloads the image as 'localImage.jpg' and overwrites the previous image:

I cannot find any pod or libraries written for Swift to implement a single-user OAuth so that I can let the iOS make POST statuses/update requests to my own account without having the users logging in.

Users don't need to log in as the tweets will be updated on my own account.

• How can I implement this sort of Twitter-bot on iOS app using Swift?
• Also, what should I set for the callback URL?
• Can I set a dummy callback URL?

I have been trying to follow the tutorials to get flask apps to run on Heroku, like this one: https://dev.to/emcain/how-to-set-up-a-twitter-bot-with-python-and-heroku-1n39.

They all tell you to put this in your code in a file server.py:

I'm trying to set up a Google Cloud Function that mirrors a python script github repository. I have already successfully implemented the function without github mirroring, but for some reason when I test the function a project where I'm using mirroring I get the error listed in the title.

The method header for the function I'm calling in my main.py file is below:

def post_tweet(data, context):

I have the context param in the header, so I'm not sure why it says I'm missing the argument.

Edit: As requested, here is the complete code.

I am using the Twit API for Node.js, and have hosted my code on Heroku, which is where it is currently running from. I followed Daniel Shiffman's tutorials from : http://shiffman.net/a2z/twitter-bots/ and http://shiffman.net/a2z/bot-heroku/

I would like my bot to go to https://en.wikipedia.org/wiki/Special:Random and "get" the title. I would then post the title as a tweet. After some research, it seems that I would like to do something called webscraping. Let's say that the title of the wiki page resides in the title tag in the html file in the head. Does anyone know how I can access the url, and get the info I need? I'm not sure where to start. Search results on stackoverflow led me to outdated answers about using jquery and a yahoo api. A solution in javascript would be helpful, so that I know it is compatabile with heroku

I am trying to only fetch the text of the tweets for a twitter bot I am working on (keep in mind twitter's API docs are worse than Oracles, which I never thought that was possible, anyway). I was using the following link to make my bot https://community.risingstack.com/node-js-twitter-bot-tutorial/

I assume that it is within their randomTweet function where they get the index from.

I'm new to javascript and can't figure out how to solve this problem. I'm currently trying to create a little personal twitter bot that 'alerts' me on new tweets, see new followers etc. I'm writing this bot with node.js and the npm package Twit. I'm currently trying to make a function that creates new Tweets. My problem is that i get a error from node.js if i try to run my code.

Here is my bot.js file
