How do I fix an AxiosError message: 'Request failed with status code 429'?
This AxiosError message means that the server you are trying to access is blocking your request due to too many requests being sent to it. This is known as a "429 Too Many Requests" error. In order to fix this, you may need to slow down the rate at which you are sending requests, or make fewer requests overall.
To slow down your requests, you can use setTimeout() function, which will introduce a delay between each request. For example, if you are using a loop to make multiple API calls, you could add setTimeout() to the loop to introduce a delay between each request. In the following example, we introduce a delay of 1 second between each request:
javascript Copy code
const apiUrl = 'https://example.com/api';
const data = [{...}, {...}, {...}]; // data to be sent with the request
data.forEach((item, index) => {
setTimeout(() => {
axios.post(apiUrl, item)
.then(response => {
console.log('Request succeeded:', response.data);
})
.catch(error => {
console.log('Request failed:', error);
});
}, index * 1000); // delay the request by 1000 milliseconds for each index of the array
});
Alternatively, you can try to reduce the number of requests you are making overall. You can do this by batching requests together, or by only making requests when necessary.
Here's an example of batching requests using axios-all package. This package enables you to send multiple requests in parallel, but limits the number of requests at once:
javascript Copy code
import axios from 'axios';
import axiosAll from 'axios-all';
const apiUrl = 'https://example.com/api';
const requests = [
axios.get(apiUrl + '/endpoint1'),
axios.get(apiUrl + '/endpoint2'),
axios.get(apiUrl + '/endpoint3'),
axios.get(apiUrl + '/endpoint4')
];
axiosAll(requests, { maxContentLength: Infinity })
.then(axios.spread((...responses) => {
// handle success responses here
}))
.catch(error => {
console.log('Request failed:', error);
});
In this example we're sending 4 requests in parallel with axios-all package, but only two will be executing at once.
Remember that there's a chance that introducing a delay might not work in all cases, especially if the server rate limit is hardcoded. In such cases, you'll need to contact the API provider for a higher rate limit or other possible solutions.

AI stands for Artificial Intelligence. AI bots are able to learn from conversations with users and expand their knowledge this way.
SheCodes Athena will help you with technical questions about your code using artificial intelligence to find the answer. Imagine a super powerful human who has memorized everything on the internet and can access that knowledge in a matter of seconds. π€―
SheCodes Athena can answer most coding-related questions, even complicated ones! It can even find bugs in your code and tell you how to fix them in just a few seconds. Impressive, right?
Just remember we're still in testing mode so the AI may return strange or incorrect replies. Feel free to message us if this happens!
SheCodes Athena can only reply to coding-related technical questions. The same type of questions you would ask in the channels on Slack.
For questions that are not coding-related, write us here π
You should treat Athena like a SheCodes team member, so always be polite! π Ask your questions as detailed as possible, just like you would do on Slack.
Here are some examples:
- Prettier isn't working on my VS Code. How do I fix this?
- How do I make bullet points with different colors using the list element?
- My code in Codesandbox is having some issues. Can you please tell me what the issue is? [Include the link to your Codesandbox]
For now, SheCodes Athena is limited to 5 questions per day for each student.
In that case, you can either ask SheCodes Athena a follow-up question, or you can post on the designated weekly channel on Slack!
Our technical assistants are still available on Slack and are always happy to help! ππͺ
Remember, questions are limited to 1000 characters.
- If you're working with an HTML file: Post a snippet of your code related to the issue you're having (just copy the code and paste it into the question box).
- If you're working with Codesandbox: Good news, you can just post the link to your Codesandbox and the AI Assistant will be able to view your code.
- If you have a longer question that would require an entire HTML file or more than 1000 characters, post it in the designated weekly channels on Slack! π
Athena was the Greek goddess of wisdom, among other elements. She received her name from the city of Athens, which she is known for protecting.
Much like the goddess Athena, SheCodes Athena is also incredibly wise and can solve complicated coding puzzles in a matter of seconds! π
Not likely. AI can automate tasks and make developers' jobs more efficient but it can't fully replace the human ability to deal with complex software. And AI will still require human developers to supervise and improve it further.
So developers may see their tasks change but they won't be replaced by AI. π©βπ»π€π»
