Hi Team,

After updating to v4.18.01 we are unable to fetch analytics data.

Management server logs:

2018-04-04 17:36:44,527 org:sei env:integration qtp1491522744-66 ERROR c.a.a.d.i.DataAPIResourceHandlerImpl - DataAPIResourceHandlerImpl.getStats() : Exception while getting stats Invalid filter expression, found - )

com.apigee.rest.framework.ValidationException: Invalid filter expression, found - )

Thanks!
