Axios Post Works but Responds with Network Error
Problem
I searched for this here, around the internet and I went and signed up in the chat but no one's there. No response in a day. Summary I'm learning so excuse my newb code. I'm using async functions with axios that all work except for one. This one did work before as I never saw this error come up when I implemented it. The `updateItem(item)` method is the one giving an error. What's weird is that I was using `axios.put` no problem but was getting an invalid verb error. Switched to `axios.post` and it does work, it hits the method and sends the item and when the method is finished an Ok(200) response is returned. But an error is thrown on the `axios.post` call of a network error. I'll show the code and error below. [code block] Context - axios version: v0.18.0 - Environment: Windows 10, Edge 41.16299.666.0, Chrome Dev 71.0.3573.0 (Official Build) dev (64-bit), and Regular Chrome latest version

1 Fix
Resolve Axios Network Error on Post Request
The network error during the Axios post request may be caused by CORS (Cross-Origin Resource Sharing) issues, incorrect URL endpoints, or the server not properly handling the request. The switch from `axios.put` to `axios.post` may have changed the expected behavior on the server-side, leading to this inconsistency.
Awaiting Verification
Be the first to verify this fix
- 1
Check the API Endpoint
Ensure that the URL you are posting to is correct and accessible. Verify that the endpoint is configured to accept POST requests.
typescriptconst response = await axios.post('https://api.example.com/update', item); - 2
Inspect CORS Configuration
If you are making requests to a different domain, ensure that the server has the correct CORS headers set. The server should include 'Access-Control-Allow-Origin' in its response headers.
httpAccess-Control-Allow-Origin: * - 3
Handle Network Errors Gracefully
Add error handling to your Axios request to capture more details about the network error. This can help in debugging the issue.
typescripttry { const response = await axios.post('https://api.example.com/update', item); } catch (error) { console.error('Error:', error.message); } - 4
Check Server Logs
If you have access to the server, check the logs to see if there are any errors being reported when the request is received. This can provide insight into what might be going wrong.
bashtail -f /var/log/api.log - 5
Upgrade Axios Version
Consider upgrading to a more recent version of Axios, as there may have been bug fixes or improvements related to network handling since v0.18.0.
bashnpm install axios@latest
Validation
Confirm that the network error no longer occurs by testing the post request again. Check the console for any error messages and ensure that the server responds with a 200 OK status.
