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.

01:12 You can monitor your usage in the Claude Console, and you need to always make sure you set max_tokens to a reasonable limit. You can also save up your tokens by using concise prompts to reduce costs during development.

01:27 And that is for your cost awareness tips. Next up is the conclusion and summary of everything you’ve done in this video course.
