I'm trying to define a default rule in a small module based on Commerce Price Table and Commerce Rules Extra. The rule is to set price based on the quantity of produtcs that contains a partial sku in the current order and the price table of the line item.
I'm new to Rules... and commerce. I'm not sure if I set the default rule correctly to get the current order or if the error is in the definition of the action (or if it's to late at night for me to see it!).
The error I got : Error: Missing configuration for parameter commerce_order.
Here is the current state of the code:
/**
* Based on Commerce Price Table and Commerce Rules Extra
*/
/**
* Implements hook_default_rules_configuration().

function commerce_price_table_sku_contains_default_rules_configuration() {
