Searching record with Invoice_Number working only one Id

Searching record with Invoice_Number working only one Id

Dear Sir,

I am trying to get record with Invoice_Number, but it returns with no content. If I provide Invoice Number "OT100585" then it returns data there. But for all other Invoices such as "FABS000559" which is available on my zoho account, it return No Content. I generated a fresh tokens for it. those worked find but end result is same. Can you guide me where I am making mistake.

Regards
