Moowoodle Woo Commerce Scheduled Action Fail

I do like this plugin. I have just swapped back to it from Edwiser. So many issues with Edwiser.

However

I’m getting a scheduled action fail with the moowoodle and the subscriptions. When I try to cancel a subscription the site gets a critical error.

Everything else seems to be OK.

Here is what I see in the woocommerce log.(I don’t understand it but I’m sure someone will).
