Invalid background modes error message when submitting to the App Store

You should open your apps info.plist in Text Edit, find the background modes section and see if there is anything strange or off about it. If you can't figure it out from there just post the contents of the plist in your question.

sorry i can not comment so i want to clear my query on this.

My app need to work in background mode for push notification & location.

I am facing same issue & i am unable to get what is wrong in this.

Thanks

Updated: I then found that Removing the "Location" attribute which was added manually which was not required once added in capabilities section. (for new versions of Xcode the provision is given in capabilities section under background mode to configure that your app is using background mode for location, push notification etc.)
