This scenario relates to FlexCard preview behavior and data mapping issues.

B. There is no Salesforce record for the FlexCard based on the RecordId in the layout's Test Data Source Settings – If the test record does not exist, the FlexCard will not display any data during preview. This is a common setup mistake.

C. The Data Node field for the FlexCard is empty – The Data Node field must be set correctly to match the JSON node where the expected data resides. If it is empty or incorrect, the FlexCard won’t bind data to UI elements.

Incorrect Options:

A. Even if the RecordId is from a different record type, as long as the data structure aligns, it would still render; it’s not a definitive reason for the card failing to display.

D. Attributes are not required to display field values directly; they are used for passing data between cards or from context, not for direct field rendering.
