ServiceNOW Connector failures (unexpected token e) error


During the initial configuration of ServiceNow Connector to the vRO server you may have a lack of functionality of the product and see a similar error in vRO logs: "Unexpected token e".  This could be present in the vRO workflows under the SovLabs > ServiceNow Connector folder in the vRO client. Specifically in either the "Create SovLabs_ServiceNow_Host" or the "Request vRA Catalog Item" workflows. 


The cause is due to the SovLabs Connector Update Set version being higher than the SovLabs plugin version in vRO. There is a dependency on the call made from the MID Server ECC Queue to the expected inputs to the vRO workflows.  The Update Set version should always be equal to or less than the vRO plugin version to avoid the above translation issues.
