What is Microsoft365Defender-20 in Siemplify, and why does the same script work in staging but fail in production with the error: "File for Microsoft365Defender-20 doesn't exist."?

The script depends on MicrosoftDefenderATPManager.py and custom_constants.py.

It's working in staging.

In production, the same script fails before execution, suggesting the integration isn't recognized.

Hey @vanitharaj1208 , 

Staging and Prod envs are isolated from each other. Considering that this is the custom code, then it can just be that not everything that was done in staging was promoted to prod. Microsoft365Defender-20 is not an official file, so it looks like there were additional custom tweaks done to the integration.
