Hi All,

 

 

 

I tried to implement the profile tool in one of my sites, but I got this error “Unhandled exception: 'The given key was not present in the dictionary.' in activity '1.72: Cast<Object[]>'.”

 

How could I solve this? I used this workflow below and it was working fine.

  Hi Rawan,

   

  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,

  Hi Malcolm,

   

  Thank you for your answer, I have two sites and the two sites have the Profile tool

   

  The profile tool in the first site is working fine, but I got the error in the second site.

   

  I noticed that when include the DEM for the second site in the map service for the first site the profile tool works fine. But when I published the DEM for second site in a new map service I got the error.

   

  I use the same ArcGIS server for both map services (the same properties applied on both services), what might be the cause of this problem?
