nginx 400 bad request

[Vishwas Bm]

Hi.

I am using nginx 1.22.1 and for some requests from client, I am seeing
below 400 bad request errors.

Below are some error messages:

"log":{"message":"225#225: *8413018 client sent invalid method while
reading client pipelined request line, client: 10.178.111.18, server: _,

400 150 [-] [-] 0 10.577 [] - - - - b1d1932b3a43ced62c2ebfa80d435092"}}


Is there any way to decode this or Is the garbled data itself causing nginx
to say 400 errors ?
Can someone help me with this ?

*Thanks & Regards,*
