I want to update a numeric type item used in Events in CRM with a function.

I want to update a numeric type item used in Events in CRM with a function.

Hello. 

I am trying to use a function to insert a number into a numeric type item in Events in CRM, but I am not succeeding.
I can update other items such as one line of text with no problem.

How do I pass a value to a numeric item to update it?

The image below shows the data from an api response with a value in a numeric field.

  2. {
  3.   "data": [
  4.     {

  6.       "receipt_no": 1111111,

  8.     }
  9.   ]
  10. }
↓This is the function I am trying to execute
  1. event_info = {"receipt_no":1111111};
  2. response = zoho.crm.updateRecord("Events",record_id,event_info);
