How to access custom fields of invoices using Zoho Deluge?

Question

I'm trying to access the custom fields of my invoices and I'm getting the following error:

Any ideas on how to solve this?

Answer 1

To help debug the issue:

• display the values in invoiceID and test2 and make sure they are not empty or zoho numbers (rather than strings)

  info invoiceID;   
  info test2;
  

• Try running the same url in a browser and/or curl to see if the behavior is the same or successful.

• Try putting a 'try/catch' around the invokeurl cmd. Sometimes (but not always) the catch(err) will report more specific error information.

  try {
      webhooktest = invokeurl
      [
          url: "https:example.org?invoice_id=" + invoiceID + "&tips_ncf=" + test2
      ]
      info "Webhooktest: [" + webhooktest + "]";
  }
  catch(err)
  {
      info err;
  }
