zsh: number expected while using `git push --set-upstream` command

I am getting zsh: number expected whenever I`m running the following command:-

Command - git push --set-upstream origin branch_name

I`m using Oh My Zsh as my terminal in MacBook Pro with M1 chip.

I even tried another command like git push -u origin my_branch, but this also not working giving out the same error message zsh: number expected

More on use of --set-upstream here & why do we need to do it all the time is here.

I got the solution for this issue:

Earlier I was running git push --set-upstream origin branch_name, with some library name in the branch name within the brackets.

For instance: git push --set-upstream origin resampling(asyncio)

What I found out is, () usually treats the content somehow differently.

And I was having zsh: number expected error as it was expecting a version number for the mentioned library.

To resolve this, I made a new branch and removed () from the branch name & the same command git push --set-upstream origin branch_name worked fine.

Hope this answer would be helpful for the community.
