Resolution

The message is a warning although not very good warning the log entry (Invalid sync response) is not an actual failure. It just means that there was an empty sync response. The empty sync response occurs when there is nothing to sync. 

The problem is simply that this log entry has too high of a severity, and there is no policy handling a blank response vs a failed response. The workaround was provided to lower the severity of this specific audit entry from WARNING to INFO to reduce the excessive entries seen in the logs. 

The current workaround is as follows: 

I was able to suppress this in my lab environment by changing the offending "Add Audit Detail" assertion from WARNING to INFO. Here are the steps: 

1. From within Policy Manager, open the "Portal Sync API" policy. 
2. Find the assertion that is: "Add Audit Details: "Invalid sync response" (this was line 32 in my policy). 
3. Open the assertion, and set the Level to INFO. Click OK. 
4. Save and activate your policy
