If you're not seeing logs or Crashlytics alerts, the issue might be in several places - either in your code, environment variables, or even Crashlytics settings.

Debugging Steps:

1. Logging: Insert debug logs throughout your Cloud Function to trace the flow.

   console.log("Function started");

2. Environment Variables: Make sure the environment variable for the Discord Webhook is correctly set up and accessible within your function.

   console.log(process.env.YOUR_DISCORD_WEBHOOK_ENV_VARIABLE);

3. Permissions: Make sure your Cloud Function has the proper permissions to interact with Crashlytics.

4. Crashlytics Setup: Ensure Crashlytics is correctly set up to send alerts.

5. Manual Trigger: Try to manually trigger the Crashlytics alert to check if the problem is with Crashlytics or your Cloud Function.

6. Firebase Function Logs: Check the Firebase dashboard for logs regarding your function.

Here is a skeleton example to debug:

exports.myFunction = functions.https.onRequest((request, response) => {
 console.log("Function started");
 console.log(`Discord Webhook: ${process.env.DISCORD_WEBHOOK}`);
 
 // Your code here
 console.log("Function ended");
});

This way, you can trace the function's execution and identify any issues.
