Unsupported system order by: ${params.key}

Error message

Unsupported system order by: ${params.key}

What it means

A provider-resolution guard in the system order-by provider: it looks up OrderByProvider('system:' + params.key) in the framework, and this fires when no such provider is registered. It means the sort config names a system order-by key that is not supported in the current build; the interpolated value is the unsupported params.key.
