does the error object always have a response ?

[jmls]

I am trying to write a set of unit tests , and using nock to mock the request from got.

I am trying to test if the system catches and handles http errors, so I am using nock to reply with 404, 501 etc

With every error I throw, there always seems to be an "e.response" . However, the docs say

Additionally, the errors may have request (Got Stream) and response (Got Response) properties depending on which phase of the request failed.

So, getting to the title of the issue - does the error object always have a response ? If not, does anyone know how to use nock to simulate that particular failure ?

The docs specify those who do have them and those who don't. For example: https://github.com/sindresorhus/got#gotparseerror

Are there any others it is missing from on that page?

Feel free to check out the source code - I don't remember, I always check the source code :)

@szmarczak When response is missing, what is the correct way to get the HTTP version that was used for the request from the RequestError object? It's not under e.options.

[szmarczak]

error.request.socket.alpnProtocol or something like this.

I printed e.options and e.request and httpVersion isn't available. It is available for errors that have e.response though.
