Azure Functions can throw exceptions if your code isn't handling errors gracefully. Ensure proper error handling with try-catch blocks and logging. Check your Application Insights logs for detailed error messages. Consider adding a global exception handler.
Conflicts between different library versions can lead to unexpected behavior. Use a package manager (like npm or yarn) to manage your dependencies and ensure version compatibility.
Functions may time out if they are running for too long. Increase the timeout setting in your function configuration. Optimize your code to reduce execution time.
Connect your function to Application Insights for detailed monitoring, tracing, and exception analysis. Set up alerts for critical errors.
Use VS Code's remote debugging capabilities to step through your function's code in real-time. This allows you to identify the exact location of the issue.
Implement comprehensive logging throughout your function. Use different log levels (Debug, Info, Warning, Error) to track the flow of execution and identify potential problems.
