Books Custom function - Not executing..

Books Custom function - Not executing..

Use case :
Module involved = Invoice
When an Invoice is "Approved", the "current date" is more than "n" days and the "Amount" to be received is more than 0
I want a cliq message to be triggered in a channel and to be executed Daily(Scheduled) at 10:30 am.
That is only if it meets the condition.

I have a custom function written. But daily it is giving an error (failure) when it gets executed.

I am attaching the script. Can anyone help me? I have contacted the ZOHO team n number of times and so far the team have not come out with any solution.
