FH10 — Missing resource or no columns

Group: Structure · Severity: error · Run by: validate and lint

A ViewDefinition must declare the required resource and must produce at least one output column. An empty resource or a view whose select tree yields no columns is rejected.

Example

No columns anywhere — FH10:

{
  "resource": "Patient",
  "select": [{ "column": [] }]
}

error [FH10]: ViewDefinition produces no columns

A missing/empty resource reports ViewDefinition is missing the required resource.

Fix

Set the resource (e.g. "resource": "Patient") and define at least one column.
