This validation ensures that every Segment call has a userId, anonymousId, and context object with a nested `"device": { "advertisingId": "e23sfsdf"}` object.

This means you can’t use regex to prevent matches with a specific following character or expression. But, you can use `not` in the regex of your JSON schema to generate violations when a property key or value doesn't match the provided regex pattern.
