I'm not sure what issue you're trying to describe here. The exception tells you the problem that contextual actions (emphasis on context actions) need an icon. That it's being thrown means you haven't provided one. My assumption is you think the default icon used for initialisation is to related to this and it's not as that is for the notification action

[MaikuB]

Closing as there's been no more response on this and as explained in previous message, the exception explains the cause of the issue
