413 Payload Too Large Error for under 5kb post data

[arasan-goaugment]

Summary

I've developed the app using Next.Js and that's in LIVE since a year. Now I got 413 error from LIVE version which was worked fine earlier. The PUT method API has 690B post data and there is no file uploads in entire app. So this API also don't have any files on post data. How can I resolve this? Kindly help to avoid this 413 error. Thanks in advance
