Hi @CHillR ,

Welcome to the Microsoft Q&A Platform! Thank you for asking your question here.

To troubleshoot why your function app endpoint is not triggering as expected, you can utilize Azure Functions diagnostics. Here’s how to proceed:

• Go to your function app in the Azure portal.
• Click on "Diagnose and solve problems" to access Azure Functions diagnostics.
• Use the search bar to input keywords related to your issue, such as "function app not invoked" or "trigger failures," to locate relevant diagnostic reports.
• Review the provided diagnostic reports, which will display status icons indicating any specific issues with your app, along with detailed descriptions of the problems, recommended actions, and associated metrics.
• If you encounter specific error messages, check the "Function Execution and Errors" section under "Function App Down" or "Reporting Errors" to identify the line of code that may be causing exceptions or errors.
