We have recently upgraded Appian environment to 16.1. However, after upgrade the shpInvoke() function has stopped working. For all the requests it is giving one response.
[success:false,result:,error:[code:[category:0,namespace:1,detail:0],title:sharepointinvoke function error,message:The external server for this system [key=SharepointExternalKey] generated an exception when calling a function [shpInvoke]. Details from external system: java.lang.IllegalArgumentException: Not a JSON object: ,detail:]]

It is giving the same response even for invalid tp credentials. I tried using same code in 7.9 and it is working fine.
I have also verified that SharePoint server is Accessible from Appian server and I am able to telnet it. Any pointers please?

Hi Tajinder,

Are both requests (7.9 and 16.1) coming from the same network? Meaning, are they both on premise? Also, does this work when you go to the URL from a browser? Have you taken a look at the IIS logs? Perhaps that can give us a little more detail on the response from the sharepoint server. I presume on the sharepoint side, there aren't any errors when the credential is correct?

Hi Vamsi, Yes the rest service is working fine in the browser. Appian server log is giving the same error as pasted above. Also I have included web-parts in SharePoint server and they are running fine. Its just that after upgrade shpInvoke() stopped working.

We also tried fetching the documents from SharePoint using shpInvoke() function, but we faced the same error
[success:false,result:,error:[code:[category:0,namespace:1,detail:0],title:sharepointinvoke function error,message:The external server for this system [key=SharepointExternalKey] generated an exception when calling a function [shpInvoke]. Details from external system: java.lang.IllegalArgumentException: Not a JSON object: ,detail:]]
Please could you suggest on this.
