Hi @Mike my name is Habib I might have a good solution for you please accept this answer if this helped.

Yes, error handling is an important aspect of any application development, including Forge Apps. Here are some best practices for error handling in Forge Apps:

1. Use try-catch blocks to handle errors: In your code, wrap any code that may throw an error in a try-catch block. This will allow you to catch any errors that occur and handle them gracefully. For example:

```
try {
  // code that may throw an error
} catch (error) {
  console.error(error);
  // handle the error
}
```

2. Return appropriate error messages: When an error occurs, return an error message that is clear and informative. This will help users understand what went wrong and how to resolve the issue. For example:

```
catch (error) {
  console.error(error);
  return {
    statusCode: 500,
    body: {
      message: "An error occurred while processing your request. Please try again later."
    }
  };
}
```

3. Use HTTP status codes: When returning error messages, use appropriate HTTP status codes to indicate the type of error. For example, use a 400 status code for user errors, such as invalid input, and a 500 status code for server errors, such as database connection failures.

4. Log errors: Use a logging library or service to log errors that occur in your application. This will allow you to diagnose issues and monitor the health of your app. For example:

```
const logger = require("@forge/logger");try {
  // code that may throw an error
} catch (error) {
  logger.error(error);
  // handle the error
}
```

5. Test error scenarios: When testing your app, make sure to test error scenarios to ensure that your error handling is working correctly. Test scenarios such as invalid input, network failures, and server errors.

By following these best practices, you can ensure that your Forge App is robust and reliable, and can handle errors gracefully.

I hope this helps you.

Thank you
