What should you always do first when testing if the data source is working in the OmniScript Designer?

• A. Save the OmniScript
• B. Run a test with dummy data
• C. Disable validation
• D. Add the ContextId to the {Data} modal

Answer: (D)

When testing a data source in OmniScript Designer, you need a defined data context to drive the test. The ContextId in the {Data} modal identifies which data context the data source should use when you preview or test. Setting this context establishes the link between the test payload you provide and the data structure the data source expects, so the dummy data can be applied correctly and the results can be simulated accurately. Without a ContextId, the test has no defined context to map to, which can lead to failing or meaningless test results. Saving the OmniScript, testing with dummy data, or turning off validation don’t establish that testing context, so they don’t reliably verify the data source. Adding the ContextId first ensures the test runs against the correct data path.
