Aggregator response could not be parsed as JSON

#1

I am trying to troubleshoot the following error message we are receiving in our mobile app - (iphone/ipad):

2016-06-30T11:04:43.18-0500 [App/0] ERR [response-validations.js]: {-dqcqgwcvoj5g0b4HdtzFj5, 212559547, get-outage-by-id, outages} aggregator response could not be parsed as JSON:

In the UI- the snack bar message states:
There was a problem with your response: 500, The aggregator response was invalid.
