Possible error in version.schema.json?

[flcdrg]

I created a new version.json file (following the instructions in https://github.com/AArnott/Nerdbank.GitVersioning/blob/master/doc/versionJson.md ).

Editing this file in VSCode, the following error is logged, which I take to mean that there's an issue in the regex?

[Error - 9:48:26 AM] Error while validating file:///c%3A/dev/git/MyProject/version.json: Invalid regular expression: /^v?(?<major>0|[1-9][0-9]*)\.(?<minor>0|[1-9][0-9]*)(?:\.(?<patch>0|[1-9][0-9]*)(?:\.(?<revision>0|[1-9][0-9]*))?)?(?<prerelease>-(?:[\da-z\-]+|\{height\})(?:\.(?:[\da-z\-]+|\{height\}))*)?(?<buildMetadata>\+(?:[\da-z\-]+|\{height\})(?:\.(?:[\da-z\-]+|\{height\}))*)?$/: Invalid group

I'm not seeing this error when I try in VS Code. And when I copy and paste the regex shown in my schema file, or the one in your error message (which are equivalent, modulo the JSON escaping of backslashes) into https://regex101.com/ in Javascript mode, no errors are reported. Can you file a bug against VS Code (and link it here)? Thanks.
