What is the best way to develop in deluge?

Hello fellow developers,

I want to ask all of you a question: What is the best way to develop with deluge in a daily basis? I mean. Most of the time I am making tests with functions and with real data, but when I am debugging, a lot of the times nonsense errors appear like "XXX connection dont exist" or "JSONobject not found".

I didnt get confirmation from Zoho but I think this errors come from the system itself because the protections are activated thinking they are attacked or something similar. I know this because if I wait some minutes, with exactly the same code, the errors dont appear anymore. Also, sometimes I get this error {"code":43,"message":"For security reasons you have been blocked for some time as you have exceeded the maximum number of requests per minute."}

So my question is: How can I avoid this errors? I usually debug in the apps like Books or Inventory. Is there a way to create a sandbox or something similar in this apps? I know in CRM I can create one, but in Zoho Finance where I do most of my work it is not possible.
