Describe your question

Github has updated their RSA host key and it is causing errors in my workflow when executing this action to send my docs to an external repo. Are there any configuration changes I need to make on my end or would those need to be made in this package?

From the Github announcement:

GitHub Actions users may see failed workflow runs if they are using actions/checkout with the ssh-key option. We are updating the actions/checkout action in all our supported tags, including @v2, @V3, and @main. If you pin the action to a commit SHA and use the ssh-key option, you’ll need to update your workflow.

Thanks for updating @peaceiris. Do you happen to know if the host key verification error is on my side or yours?

Are you running your job on a self-hosted runner that keeps launching? If so, please try adding ssh-keygen -R github.com before the deploy step. If the deployment is successful with this method, try removing the command. After that, I believe you should be able to deploy without any issues as before.

      - run: ssh-keygen -R github.com
