What is the reasoning for a Request FSA with error flag? (vs a Failure FSA)

[barrystaes]

As i understand now - when a REQUEST FSA gets fired, this can result in a:

• REQUEST FSA with error flag (for example when the API request cant be made)
• SUCCESS FSA (for example for API response 200 OK)
• FAILURE FSA (for example for API response 404 Not Found)

But in my view one REQUEST FSA should result in (only and) exactly one FSA, either SUCCESS or FAILURE.

I haven't actually used it, but i dont really understand the first one. Whats the argument for not returning a FAILURE FSA in that case?

@barrystaes This is an issue that I struggled with — see this comment of mine. The solution that I came up with might not be to everyone's taste nor even the most logical one. I think a thorough discussion is in order before we push out a v2.

Pinging #26, since it is relevant to this issue.

I am also confused. When I get an API request error like this :

{ 
 [RequestError: request to https://xxxxx failed, reason: self signed certificate]
 name: 'RequestError',
 message: 'request to https://xxxx failed, reason: self signed certificate' },
 meta: undefined,
 error: true }

The FAILURE FSA is not triggered. I see this error by logging on REQUEST FSA.
So my question is, when actually FAILURE FSA gets triggered ?

Found this when searching for how to customize the action payload when a REQUEST FSA is dispatched with an error flag. Seems you can't? For example, if I attach a key property to the initial REQUEST payload, there is no way to correlate that key's value back to the request that failed?

So my question is, when actually FAILURE FSA gets triggered ?

@aris-b a FAILURE FSA is triggered when the response is not 200 OK, and if the response was 200 OK expect a SUCCESS FSA.
If the request could not be made at all, expect a REQUEST FSA with error:true. This behavior is documented at lifecycle in readme.md and its also outlined in the first post of this issue..

@danludwig Have you looked into using the meta property, which is there for the purpose of adding metadata to use later.
