I attempted to clone a Git repository, which contains the main 'master' branch. Additionally, I created a new branch named 'feature1' within the same repository. Upon switching from the 'master' branch to the 'feature1' branch, I implemented a set of new features. Following the completion of these changes, I performed the following actions:

git add .
git commit -m "my_message"

this is what i get by doing:-

git remote -v

origin  https://github.com/raghavpain/simplepractice.git (fetch)
origin  https://github.com/raghavpain/simplepractice.git (push)

but when i'm trying to push my change by doing this :-

git push origin feature1

i'm getting this error :-

mohit@mohit:~/okk/git_check/simplepractice$ git push origin feature1
