Hi Phuwasate, Jongchana,

It seems like there's an issue with the Azure Cosmos DB input binding causing a 500 Internal Server Error when you call the function's URL. Let's troubleshoot this together.

Firstly, let's carefully review the code and configuration of the Azure Cosmos DB input binding you've added.

Here are some steps to help diagnose and fix the problem:

1.Review Function Code: Double-check the JavaScript code in your Azure Function to ensure it correctly handles input from the Cosmos DB binding.

2.Check Binding Configuration: Verify the configuration of the Azure Cosmos DB input binding, including the connection string, database name, container name, document ID, and partition key.

3.Verify Access: Make sure your Azure Function has the necessary permissions to access the Cosmos DB account. Check the access rights and connection string used in the binding.

4.Inspect Function Logs: Look at the logs of your Azure Function for any error messages that might explain the issue more clearly.

5.Test Binding Independently: If possible, test the Azure Cosmos DB input binding separately to confirm it's configured correctly and can retrieve data from the database.

6.Error Handling: Ensure your function code includes proper error handling to deal with potential issues like connection errors or missing documents.

Once you've gone through these steps and identified any problems, you can adjust your setup accordingly to fix the issue.
