ApplyJSONFilter doesn't work on PowerBi Report Server, but does on PowerBi Online

[Anonymous]

Okay, so I'm not entirely sure where the issue is, but it seems like I can't call a selfFilter using applyJsonFilter, when my report is deployed on the PBI Report Server. 

Here is the response header, and failed request. 

Anyone know whats going on? Is there an incompatibility between applyJSONFilter and the PowerBi Report Server? This all seems to work well on PowerBi Online.  Any help appreciated, thanks.
