Create a task on a account via function

Create a task on a account via function

I'm trying to create a function for accounts that creates a task based on certain conditions and processes (that's why it's not possible to just use a workflow). Everything seems to be working fine, with the exception of the task creation. Does anyone knows what am I doing wrong?

On arguments, there is:
      id  > Accounts - Id
      owner > Accounts - Account Owner
      company > Accounts - Account Name
      

  3. // Create Task
  4. taskmp = Map();
  5. taskmp.put("Subject","First Contact");
  6. taskmp.put("Owner",owner);
  7. taskmp.put("Priority","High");
  8. taskmp.put("Status","Not Started");
  9. taskmp.put("Due_Date",today.toDate());
  10. taskmp.put("Details","Testing Details");
  11. taskmp.put("Account",company);
  12. taskmp.put("What_Id",id));
  13. taskmp.put("$se_module","Accounts");
  14. task = zoho.crm.createRecord("Tasks",taskmp);
  15. info taskmp;
  16. info task;
