Error handing while use client script in zoho crm for Cannot read properties of undefined

Error handing while use client script in zoho crm for Cannot read properties of undefined

Hi Folks, I´m using client script to get values from Accounts module to Quotes module using this piece of code

var accountrecord = ZDK.Apps.CRM.Accounts.fetchById(account.id); 

if (accountrecord._Rating == null) {
    do someting;
}

In the console I'm getting this error message when the account record is in a middle of an appoval process and the script stop to work.


Cannot read properties of undefined (reading '_Rating')

Anyelse know how can I handling this type of errors in order to baypass the line when it ocurr? In other hand is common that  zoho crm block this records when an approbal process is working ?
