Warning: ksort() expects parameter 1 to be array, null given in drupal_group_js()

It looks like commerce kickstart has some patchset or backported D8 core code that it don't like what is added by AIS' implementation of hook_js_alter.

This is likely a bug somewhere all the core changes, but the easiest way to fix it may be to add

'browser' => '',

into the two array of javascript definitions added by ais.module->ais_js_alter().

I haven't tested that, but give it a try. If it works I'll update AIS.

Thanks,

Looks like the correct answer was 'browsers' => array() in each block.

I've commited the fix to the dev branch.
