I did commit successfully in my local repository. When I try to do:
git push https://gitlab.com/priceinsight/jmt4manager/compare/develop...2-retrieve-list-us
The URL you try to push to is total nonsense. You are trying to push to the URL https://gitlab.com/priceinsight/jmt4manager/compare/develop...2-retrieve-list-userrecord# which is a webpage that compares two branches and not the URL of a repository. The repository would be https://gitlab.com/priceinsight/jmt4manager.
