Issue with a blueprint transition using API request

Issue with a blueprint transition using API request

Hello

I have created a function in the Zoho Flow app, which should perform a blueprint transition. 

  2. par = Map();
  3. par.put("toNotifyContactForResolution",false);
  4. par.put("content","Solved");
  5. param = Map();
  6. param.put("RESOLUTION",par.toString());
  7. result = invokeurl
  8. [
  9. url :"https://desk.zoho.com/api/v1/tickets/xxxxxxxxxxxxxxxxxxxxxxxxx/transitions/yyyyyyyyyyyyyyyyyyyyyyy/perform"
  10. type :POST
  11. parameters:param.toString()
  12. connection:"zoho_desk"
  13. ];

This code is pretty simple. It works well if a ticket assigned to the Primary user. If I assign the ticket to another user, the request fails. 
{
	"errorCode": "INTERNAL_SERVER_ERROR",
	"message": "An internal server error occurred while performing this operation."
}

At the same time both of the users can perform the transition manually using the buttons in the application. The error appears only during the API request.






Could anyone help me with this issue?
Thanks
