If your GitHub account does not qualify for verification you will need to upgrade to Hobby, this can sometimes happen if your GitHub account is too new or doesn't have enough activity, among other things.

I understand but then I have to pay because I can't upload my project to the server and consume it.
I also have another question, why does Dockerhub appear and not master? How can I make master appear?

Yes, you would need to pay, unfortunately.

That is a screenshot of your database, it has nothing to do with your code deployment, code deployments can't be done on the limited trial plan.

So that's why next to Active where it says mongo and below mongo Dockerhub appears Dockerhub and not master? How can I make master appear?

As previously mentioned, that is your database, it has nothing to do with your code deployment, code deployments can't be done on the limited trial plan. You will need to upgrade to Hobby.

ok, thank you
