Error message: Value cannot be null. Parameter name: symbolData

After an upgrade to GE, a site that previously worked fine now rejects a map service with this error message 

 

Value cannot be null. Parameter name: symbolData

 

 

There aren't any null values in the symbology and all fields that had null values in them have been hidden before publishing (not that it should have made a difference if the null value existed? Other map services don't seem to mind that.)  

 

Any ideas how to fix this?

  Hi Ann, 

   

  Were you able to get this working?  I was able to load the url into my Essentials site when I tested.  I have seen similar (but not identical) cases where recycling the Essentials App pool fixes the issue.  Troubleshooting something like this, you could also try adding "?f=pjson" to the end of the service url and check to see if anything looks out of place with the in the drawingInfo property.

  I am experiencing this exact issue when trying to reference a web map that uses a couple problematic layers. Any advice?

  Dear All,

   

  do you have any suggestion how to fix this issue? Is Geocortex issue or Services issue?

  Francis, I was able to pinpoint the issue: I published the hosted service with complex symbology and got a warning that AGOL could not handle the symbology and it would be downgraded. By changing the symbology prior to publishing, I resolved this issue.

  I have also this problem.

  It happens when if you use a  sollid sybology with no outline.

   

  Then the outline will be Null.

  This is ok with Esri, but apparently not with Geocortex.
