omniauth-facebook | Facebook OAuth2 Strategy for OmniAuth

I followed the pull request from the branch to the master (devise) but I'm still having the error and I can't deploy the api to the server anymore

I also tried the solutions provided in this question but was not successful:

Latest omniauth-facebook gem breaks devise

The error:

ruby '2.6.3' gem 'rails', '~> 6.0.2', '>= 6.0.2.1'

I'm using the latest omniauth-facebook and devise together Gemfile: gem 'devise' gem 'omniauth-facebook'

Getting this error when starting the server:

/versions/2.6.3/lib/ruby/gems/2.6.0/gems/devise-4.7.3/lib/devise/omniauth.rb:12:in `': You are using an old OmniAuth version, please ensure you have 1.0.0.pr2 version or later installed. (RuntimeError)

The problem is that if I try to use older omniauth-facebook versions the server works but then the Facebook authentication stops working properly (e.g. fails including emails despite

scope: 'email', info_fields: 'email,name'

in devise.rb. )

I have tried many different version combinations of omniauth-facebook and devise. Either Facebook-authentication stops working properly or the server fails (see above).

I am trying to authenticate user to rails 6 app using omniauth. It works locally but when I deployed to heroku I was getting an error saying invalid id.

I looked around and found a post about updating the gem from just omniauth-facebook to gem 'omniauth-facebook', '1.4.0', so I did that and now it just goes back to the home page without logging in locally and on heroku I get this error:

I'm trying to download an image from an URL, the URL is from facebook. I get the URL after I signup with omniauth-facebook:

I saw a lot of similar questions here, but nothing of provided advises has helped. Every time I run cap production deploy I got error:

I picked up a 4 year old project written in Ruby 2.1.3 and Rails 4.1.8.

Very few of the gems were versioned but I've managed to get the project running locally by installing mysql2 0.3.20 as suggested in multiple other threads. Doing this required me to (on MacOS) downgrade openssl and mysql with brew install mysql@57 and brew install openssl@10.

I could then install mysql2 with by passing the correct libraries to it: gem install mysql2 -v 0.3.20 -- --with-mysql-config=/usr/local/opt/mysql@5.7/bin/mysql_config --with-ldflags=-L/usr/local/opt/openssl@1.0/lib --with-cppflags=-I/usr/local/opt/openssl@1.0/include

Everything works locally, all good.

I'm trying to deploy this project with Dokku on a Debian instance. Here's the readout from the push to dokku master including the error thrown when starting the Rails server:

I have omniauth-facebook to sign up/sign in. After signin, I want to redirect the user to the page where they hit the auth block. I'm using sign_in_and_redirect but it seems to be calling the last url, which in this case is

http://localhost:3000/auth/facebook?callback_url=localhost%2Fauth%2Ffacebook%2Fcallback

So it keeps doing: Redirected to http://localhost:3000/auth/facebook?callback_url=localhost%2Fauth%2Ffacebook%2Fcallback

And it keeps calling this callback in a loop until it crashes. Here is the omniauth controller:

I'm trying to push some modifications of my Ruby on Rails web to Heroku but it says "push rejected". The error comes after "Detecting rake tasks" and here's the message:
