This is due to Nutanix updating their API. As the creator of the Nutanix report, I have no immediate plans to update the report because I no longer have regular access to these environments. Future revisions to this report will heavily rely on people who wish to contribute to the project. I'm happy to help anywhere I can.

@SobreroD what type of Nutanix environment do you have? I have been working this week on updating the script however I have very limited access to environments to test.

Please checkout pull request #21 and let me know if this resolves your issue.
