Zoho Flow / Zoho CRM / WebHook creating a sales order error

Hi,
I'm facing a error that I can't solve.
The path begins with a external ERP sending a signal of a sales order, via webhook, to zoho flow.
In my design, I put the first step to create a contact in Zoho CRM, them create an Iten in Inventy (or update it, if already exist it), but when it goes to create the sales order, there's a field, called "product details" that don't matter what I do it just wont accept it. 

My last try was to fetch the product with the name of it, them use a custom function (

list teste(string inputData)
{
response = zoho.crm.getRecordById("Products",inputData);
return inputData.toList(";");
}

)

to take the id and put into that place, but don't acept either...
