I am created an application which puch data in Zoho CRM Contact module, everything is fine data is successfully stored at both locations Zoho CRM and Zoho Creator. 

Now i want that when i am edited any data row in Creator then corresponding Zoho CRM contact module row is also updated. So for this i am follow following post:

https://kbase.creator.zoho.com/crm/how-to-get-the-id-of-the-crm-record-that-is-created-using-the-zoho-crm-create-task

and use following Coding at Form >> Edit >> Success

1. // First i search the records according to Form Input.
2. contact_search = zoho.crm.searchrecords("Contacts","(Last Name|==|input.Last_Name)");
3. current_id= contact_search .get("Contact Id");  // i get error in this line.
4. Contact_edit_res = zoho.crm.updaterecord("Contacts",current_id,{ "Email" : input.Email, "First Name" : input.First_Name, "Email" : input.Email, });

the error comes: 

Error at line:3
The argument for the operation :'get' should be of type long/int. But an expression of type :'STRING' was found

 

I am also replace the code with doing following update:

1. // First i search the records according to Form Input.
2. contact_search = zoho.crm.searchrecords("Contacts","(Last Name|==|input.Last_Name)");
3. current_id=(contact_search.get("Contact Id")).toLong();  // i am update this line with long value returning.
4. Contact_edit_res = zoho.crm.updaterecord("Contacts",current_id,{ "Email" : input.Email, "First Name" : input.First_Name, "Email" : input.Email, });

but i am get the same error:

Error at line:3
The argument for the operation :'get' should be of type long/int. But an expression of type :'STRING' was found

I am stuck in this problem please provide me solution. Also check my update call function for CRM, is it can be work for me in which manner i am used it here.

Thanks in Advance
