My web client application is setting HTTP POST requests via fetch API.
I see that OPTIONS preflight requests are sent via debugging proxy (Charles Proxy), but they are not displayed in Google Chrome Developer Tools\Network tab.
I don't have any filters setup on the network tab. I remember OPTIONS requests being visible there, but not anymore. How do I bring them back?
Simply go to the page and open the network tab. You can see the network tab by hitting cmd + opt + j on your Mac or ctrl + shift + j in Windows. It will open up the console tab in DevTools by default. Once the console tab is open, simply click on the network tab to make it visible.
Finding the Console/Network Tab in Google Chrome:Either click the three dots in the top right of your chrome browser to open the menu. Then, go to 'More tools > Developer Tools' and then switch to the Console Tab.
HttpWatch on Windows can record the network traffic generated when a new Chrome tab or window is opened by enabling auto-recording in Tools->Options->Recording. In the new window click on the HttpWatch icon to view the network trace.
You'll need to go to: chrome://flags/#out-of-blink-cors
, disable the flag, and restart Chrome.
This is an expected behavior change according to:
