Debugging a Custom Visual in Power BI Desktop

[SupriyaChaugule]

I am developing a custom visual for Power BI Desktop and encountering some issues with debugging. The visual is not rendering as expected, and I need to identify potential errors in the code or data flow.

• Are there any built-in debugging tools or extensions to troubleshoot custom visuals in Power BI Desktop?
• How can I debug TypeScript code within Power BI?
• Is there a way to inspect API calls or interactions between Power BI and the visual?
