Isn't "422 Unprocessable Entity" the correct name?

What specific section or headline is this issue about?

422 Unprocessable Content

What information was incorrect, unhelpful, or incomplete?

I believe the title "422 Unprocessable Content" is out of date. I think the correct title should be "422 Unprocessable Entity".

What did you expect to see?

"422 Unprocessable Entity"

Do you have any supporting links, references, or citations?

Per https://datatracker.ietf.org/doc/html/rfc4918#section-11.2

The 422 (Unprocessable Entity) status code means the server understands the content type of the request entity (hence a 415 (Unsupported Media Type) status code is inappropriate), and the syntax of the request entity is correct (thus a 400 (Bad Request) status code is inappropriate) but was unable to process the contained instructions. For example, this error condition may occur if an XML request body contains well-formed (i.e., syntactically correct), but semantically erroneous, XML instructions.

I noticed this because the Rust http crate uses "Unprocessable Entity" as well:

    /// 422 Unprocessable Entity
    /// [[RFC4918](https://tools.ietf.org/html/rfc4918)]
    (422, UNPROCESSABLE_ENTITY, "Unprocessable Entity");

Do you have anything more you want to share?

I haven't followed the relevant RFCs closely in a while. Please educate me if I've gotten this wrong; if so, then the Rust http crate has gotten it wrong too.

This was changed in #24866. You can check the more up-to-date links there. (The MDN page also has a spec link to RFC9110.)

I stand corrected! Thanks!

Hi. I just encountered into this mismatch too. Too my surprise, the official document stand correct with the MDN one but at least in Chrome all 422 are labelled as Unprocessable Entity.

Do you reckon this is a Chrome issue? @Josh-Cena
Thanks in advance!

[Josh-Cena]

Yeah, very likely. I'm on vacation so I can't check, but it would be helpful to search through Chrome issues and maybe send one if nothing comes up.
