Calling ActivityEvents API from Logic Apps - Returns Empty Array

[swise001]

I've setup a Logic App that's running a Custom Connector loaded with the Activity Events API. 

The Logic App works - in that it calls the API for a single date - and returns a continuation token. 

I use decodeURIComponent - and feed the continuationtoken back to the API - and ask it to loop until "lastresultset" = true. 

The timeout is set to 60.  

The app cycles 60 times - and always returns the same result (which looks identical to the first run). 

{"activityEventEntities":[],"continuationUri":"https://wabi-us-north-central-redirect.analysis.windows.net/v1.0/myorg/admin/activityevents?continuationToken='LDIw************uMDAwWiwyMDIwLTExLTE4VDIzOjU5OjU5Ljk5OVosMSws'","continuationToken":"LDIw************uMDAwWiwyMDIwLTExLTE4VDIzOjU5OjU5Ljk5OVosMSws","lastResultSet":false}

I'm unsure why it continues to return an empty array [] each time.  

The date I've chosen is a Wednesay - and I know there should be data.

Any ideas?
