Summary of Changes

Hello @angelcaamal, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request addresses an issue in the executeFhirBundle.js sample by ensuring that API responses are correctly parsed as JSON and improving the readability of the output. By explicitly configuring the response type and formatting the console log, the sample now provides a more robust and user-friendly experience when executing FHIR bundles.

Highlights

• API Client Configuration: Explicitly set the responseType to 'json' for the API client in executeFhirBundle.js to ensure proper handling of JSON responses.
• Output Formatting: Updated the console logging of the FHIR bundle execution result to pretty-print the JSON data using JSON.stringify for better readability.

Changelog

• healthcare/fhir/executeFhirBundle.js
  • Added responseType: 'json' to the API client configuration.
  • Modified console.log(resource.data) to console.log(JSON.stringify(resource.data, null, 2)) for formatted output.

Code Review

This pull request updates executeFhirBundle.js to set the response type to json and pretty-prints the output. The changes are functionally correct. My review includes a suggestion to improve the robustness of the sample by adding error handling for the asynchronous operations.

[gemini-code-assist]

This function contains asynchronous operations (file reading, API call) that can fail. Without a try...catch block, any error will result in an unhandled promise rejection, which can crash the application in future Node.js versions. To make this sample more robust and user-friendly, please wrap the function body in a try...catch block to handle potential errors gracefully.
