I have this flow developed for a customer in which based on the dialled number of calls on zoho crm, they were able to get the Lead Source automatically.

It's a flow that saved a lot of time to them for reporting. All was done reading the calls related to a phone number entered into the system. If a call was found, we took the dialled number from the response zoho.crm.getRecordbyId("Calls", xxxxxxxxxxxxxxxxx) gave us.

The thing is that suddenly the response now doesn't give the dialled number, and the complete flow doesn't work. We never got any notification that the response was going to change, and I don't understand why they removed that valuable information from the response.

I tried using the API, but the response doesn't give the dialled number. 

Can someone please help me with this? This really took us by surprise.
