I have a problem with the Get Geometry From JSON activity

I have the following polygon description;

 

{"rings": [ [ [51.520833, -0.195543 ], [51.52086, -0.195543], [51.52086, -0.195499], [51.520833, -0.195499], [51.520833, -0.195543] ] ], "spatialReference" : {"wkid":4326}}

 

I use the Convert To JSON activity and get the following result;

 

"{\"rings\": [ [ [51.520833, -0.195543 ], [51.52086, -0.195543], [51.52086, -0.195499], [51.520833, -0.195499], [51.520833, -0.195543] ] ], \"spatialReference\" : {\"wkid\":4326}}"

 

This gets passed into the Get Geometry From JSON activity

 

Looking in developer tools I see that the output from the activity is undefined.

 

 

 

What might I be doing wrong ?

Just for info my map backdrop is in 27700 not 4326, my next task is to project the geometry to 27700

  So I think the problem is when I pass the geometry to the Project Point. If I use the rest endpoint for the geometry server I get an Invalid or missing input parameters so there must be something wrong in the json I am building
