Hello Harinath J,
Welcome to the Microsoft Q&A and thank you for posting your questions here.
I understand that you would like to fix Azure Function App API returns Internal Server Error 500.
Solution
An Internal Server Error 500 can occur due to various reasons such as database issues, server request timeouts, misconfigured servers, or noisy neighbor problems in a shared environment. To resolve this, you may need to check especially the three core areas below:
- Ensure your database is responding correctly and the connection strings are accurate.
- Verify all required settings are properly configured in the Azure portal.
- Look for unhandled exceptions in your code that might be causing the error.
In addition, use Application Insights to get detailed error logs and troubleshoot further. Also, regarding the runFromPackage
setting, it's recommended to use WEBSITE_RUN_FROM_PACKAGE = 1
for deploying functions as it improves performance and reliability. Ensure your Azure DevOps pipeline is configured correctly with either AzureFunctionApp@1
or AzureFunctionApp@2
task for deployment.
