Getting a 422 Error Code – What’s Causing It and How Do I Fix It? or Why Am I Seeing a 422 Error Code

Ugh, 422 errors are the worst. Had this happen when a form expected a number but I typed "123" (with quotes). The server freaked out.

Try using Postman (https://www.postman.com/) to test the API directly—you’ll see the raw response and might spot the issue faster.

Also, some APIs return more details in the error body. Open dev tools (F12) and check the "Network" tab for clues.
