smart-forms/questionnaire-variable-unavailable

error Reports a reference to %questionnaire or %qitem, which Smart Forms does not supply.

What it checks

Every %questionnaire and %qitem reference in a FHIRPath expression that the selected Smart Forms renderer or population evaluates: variables, calculatedExpression, enableWhenExpression, answerExpression, the cqf-expressions on item text, prefix and answerValueSet, targetConstraint, answerOptionsToggleExpression, initialExpression and itemPopulationContext.

Example

Smart Forms does not supply %questionnaire, so this variable on the Questionnaire root fails when the reference is evaluated, and %title gets no value from it.
