How to add inputs not use add-on builder?

Hello, I created an add-on using Add-on Builder and added inputs using Builder. Now I have to add new inputs to the add-in, but not use Add-on Builder, how can I do this? I am writing three Python input files using an example of how Add-on Builder does it and adding input information to the configuration files in the local directory and /appserver/ static/js/globalConfig.json. As a result, I get an error 500 - Internal server error when Splunk called TA_splunk_addon.py What is the problem?
