Troubleshooting Errors

00:00 Now that you have your Python coding assistant ready, it’s time to troubleshoot two of the most common errors and then pay attention to some security concerns.

00:08 If you come across the AuthenticationError, it means your API key is either not valid or it’s missing. It almost always gets fixed by setting the ANTHROPIC_API_KEY correctly within your environment.

00:22 Now if you end up getting a BadRequestError, it means your request format is invalid. For this, make sure your message list has role and content set up correctly.

00:33 And also make sure you’re passing the system parameter as a top-level parameter and not as a message. That’s for troubleshooting your most common errors.

00:43 Now for security concerns. The most important thing is to never hardcode your API key anywhere within your code. You need to always have your API key either within a .env file or you need to export it, just like you did in this video course, as an environment variable.

01:02 And if you end up exposing your key anyway, you need to deactivate it and then create a new one. You should also pay attention to the cost of your API calls. You can monitor your usage in the Claude Console, and you need to always make sure you set max_tokens to a reasonable limit.

01:21 You can also save up your tokens by using concise prompts to reduce costs during development. And that is for your cost awareness tips. Next up is the conclusion and summary of everything you’ve done in this video course.
