@mtruj013 Thanks for the fix. Is there a way to achieve the same outcome without making those CVSS4 fields mandatory?

[mtruj013]

@Skazitron removing allow_none=true doesn't make the fields mandatory, that's done with the required parameter. allow_none only controls whether an explicit null is valid, it defaults to false, meaning null would now be rejected if passed. I confirmed with the sec team that they do not pass these as null but rather just omit them so this parameter is not needed
