Not receiving the correct primaryKey for Azure Maps AQI

I am getting stuck here on the learn project Track global air quality with Azure Maps at unit 5 of 9. I have followed the troubleshooting on the "Exception has occurred: KeyError" since that is what is happening. I go back to copy and paste the primaryKey to see if it is the right key and I paste the key directly into the file and still get the same error. I have also used the pollution_map authentication going through the Azure Portal > Azure Maps > Pollution_map. How can I make the app run?

Thank you for your help!

    Hi ChrisFarlee,

    It sounds like you're dealing with a common issue. The "KeyError" usually means the program is trying to access a key in a dictionary that doesn’t exist, so it’s great you’re already double-checking the primary key. Here are some practical troubleshooting tips that might help:

    Check Key Naming: Make sure the key name in the code exactly matches the one in your configuration. Even small differences like "primaryKey" vs. "primary_key" can trigger this error.

    Verify Key Location in Configuration: If the key is sourced from a config file or environment variable, confirm the file is being correctly loaded and that the primary key is located where the code expects it to be.

    Use Hard-Coding for Testing: Temporarily hard-code the primary key directly in the relevant section of the code. If that resolves the issue, it indicates that the variable reference might be causing the error.

    Print Debugging: Place a print() statement right before the line where the KeyError happens to display the dictionary’s contents. This will confirm if the key is missing or if there’s another underlying issue.

    Exception Handling: Try wrapping the code in a try...except block to log the dictionary contents if the error occurs. This can help identify exactly which keys might be missing.

    If the problem persists, pinpointing the exact line causing the KeyError could help in finding a more precise solution!
