Hi @juliogitdev !

Great job—thanks for your contribution! Since this project isn’t in production, feel free to simply adjust the existing migration scripts rather than creating a new one.

Hello @juliogitdev ! A better approach would be update your remote repository and then run the following commands inside your local feature branch.

git fetch origin
git rebase origin main
