Error message on dashboard

This message appeared on top of my dashboard after updating wordpress and jetpack.
I am using buddyboss theme. All other plugins are updated too.
The only code i have inserted in header is google analytics code.

: Undefined index: script_async_handles in /home/stude760/public_html/wp-content/plugins/header-footer/plugin.php on line 66
