No url found for submodule path 'XXXXXXX' in .gitmodules

I have problem while using git in one of the platform I'm using, it shows this error while the url is already define in .git/config file:

Note:if I use master branch no error, but if I use none branch I get the error. even if the code is identical

 [core]
        repositoryformatversion = 0
        filemode = false
        bare = false
        logallrefupdates = true
        symlinks = false
        ignorecase = true
[remote "origin"]
        url = https://bitbucket.XXXXX.com/project.git
        fetch = +refs/heads/*:refs/remotes/origin/*
[branch "master"]
        remote = origin
        merge = refs/heads/master
[branch "none"]
        remote = origin
        merge = refs/heads/none

if I try to do "git submodule add URL" === error alreedy exist.
