Additional context/Screenshots

This is because per spec (https://fetch.spec.whatwg.org/#methods) methods are case-sensitive, and only some methods are normalized, but patch is not one of them.

The solution is to call method.toUpparcase() on 2 places:
https://github.com/axios/axios/blob/v1.x/lib/adapters/fetch.js#L125
https://github.com/axios/axios/blob/v1.x/lib/adapters/fetch.js#L149

Http and xhr adapters do this, probably because of the same reason mentioned above:
https://github.com/axios/axios/blob/v1.x/lib/adapters/http.js#L164
https://github.com/axios/axios/blob/v1.x/lib/adapters/xhr.js#L33
