profile tool - given key dictionary error

I am trying to implement the profile tool. It works on one site of ours but not the other. The only difference is the DEM source and the Coordinate system. I have followed this thread (link below) and still can't work out the cause. I've configured all the parameters (elevation source etc., see attached image)

Error message is:

 

There was a workflow error running activity: Exception has been thrown by the target of an invocation. Workflow 'ProfileTool' failed Unhandled exception: 'The given key was not present in the dictionary.' in activity '1.72: Cast<Object[]>'. The given key was not present in the dictionary.

 

I've populated all the custom parameters:

  Hi Peter,

   

  The Profile Tool workflow runs a series of web requests to the Identify endpoint for the DEM that you published that has height information.

   

  The Cast<Object[]> activity is trying to locate a specific named attribute out of the Identify response.  If that attribute isn't there, you will get the error "The given key was not present in the dictionary".

   

  To troubleshoot, I recommend using Log or Alert to print out the JSON that is returned.  Then, you can see if the key in the dictionary is a different word, or you can see if there is an error.

   

  You may also get this error if your DEM has no data where you draw the transect line.

   

  Regards,
