How do I fix ADF Pipeline Error 3254?

Open the AzureSynapseArtifacts linked service flagged in the error and locate the property name reported in '%propertyName;'.. Verify the property is defined and contains a valid value matching the expected data type and format.. If the value is parameterized, evaluate the expression against the failing pipeline run's parameters to confirm it resolves correctly.. Save and publish the linked service, then test the connection from ADF before re-running the pipeline.. Retry the pipeline run and confirm the activity now resolves the linked service successfully.
