Getting error in Zapier when try to create a new order in Infusionsoft

Hi,

Within the last couple of days I’ve been getting an error in Zapier when I’m using the Infusionsoft integration to create orders.

The error is:

The order could not be sent to Infusionsoft by Keap.

Fault (code 0) occurred. Message: Failed to invoke method placeOrder in class com.infusionsoft.api.xmlrpc.XmlRpcOrderService: null

Any ideas what this means?

It seems like the orders are still being created, however I’m now getting 5 duplicate orders created each time, instead of 1.

Any help greatly appreciated!
