Cannot parse the JSON schema

[easitab-owner]

With the release of PowerShell 7.4 a breaking change was introduced, "Test-Json now uses JsonSchema.Net instead of Newtonsoft.Json.Schema. With this change, Test-Json no longer supports the older Draft 4 schemas.".

PowerShell/PowerShell#18141

As 'installerSettings.schema.json' is generated with a Draft v4 this change causes 'New-EPRInstallation' to fail.

We need to generate a new schema with Draft v7 and update the installation package.

"$schema": "http://json-schema.org/draft-07/schema#",
"title": "Generated schema for Root",
Ovanför "type":"object",
Detta löste problemet. Tack Anders!
