Read JSON and Cast to FHIR Type

The Read JSON and Cast to FHIR Type step casts a JSON formatted string to a specified FHIR Type. 

Prerequisites 

This step requires the FHIR Module to be installed before it will be available in the Toolbox. 

In version 9 a dependency to the module must be created in a Project for the steps to be visible.

If the JSON string is not correctly formatted or empty, the step will cause an error.

To correct this, ensure that the JSON string is valid and mapped or entered correctly.
