When you see it

Posting JSON without setting Content-Type to application/json is the classic case. The body is fine, but the server cannot tell what it is meant to be and refuses to guess.

It also appears on uploads where a file type is not allowed. If you are unsure what type a file should be declared as, the MIME type lookup maps extensions to their correct values.
