Hi Olsztyniak, In CMDB Integration Studio (CIS), when you use a Script as part of a Data Source (usually inside a Data Ingestion Plan), the platform passes data into your script through a variable typically named:

input

1. How to View the Input Variable

Use gs.info() Logging

You can print the entire input object:

gs.info("CIS Input: " + JSON.stringify(input));

This works because in CMDB Integration Studio, the input variable is usually an object containing:

payload
data source parameters
connection values
pagination tokens, etc.

After adding this line, run the Data Ingestion Plan and check:

System Logs → All → Messages

Search for: CIS Input:

2. Use gs.print() in a Scoped App Script

If running in a scoped app (cmdb_integration_studio):

" / gs.print("Input: " + JSON.stringify(input)); / "

This appears in Background Script log output or System Logs.

3. Use the Script Debugger (best for interactive debugging)

Go to Script Debugger
Choose Scope: CMDB Integration Studio
Run the Data Ingestion Plan
Breakpoints in your script will pause and allow you to inspect variables (including input)

Summary

To see what’s inside the input variable passed to a CMDB Integration Studio script:

Method Best For

gs.info(JSON.stringify(input))	Quick logging to system logs
Using Script Debugger	Full inspection + breakpoints
Return-value logging	Seeing transformed output

Let me know how the above three points has worked for you. Or share us how you were able to fix this if this has already got the solution with your own research

In continuation here is a sample minimal script

CIS Script with Input Inspection

"/

(function() { gs.info("=== CMDB Integration Studio Input ==="); gs.info(JSON.stringify(input)); // Return required structure return { status: "success", data: [] }; })();

/"
