     - It might be occuring when there are already some changes to be staged once you launch `gitautopush`. First, run `gitautopush`, then start creating files or making changes to the existing ones. 
     - Another thing to try is to first commit and push one file manually to the repository, once you have done that and no changes are staged run `gitautopush`
