Moya request not started for one provider but works for another

Question

I've inherited an RxSwift project which uses Moya. I have a task to move a request from one backend to another. Both backends have their TargetTypes sets up just fine as they're being used extensively elsewhere.

The original request looked like this:

return accessProvider.rx
    .request(request)
    .asObservable()
    .debug()
    .flatMapLatest({ [weak self] (response) -> Observable<Bool> in
        //does some processing of the JSON
        return just(true)
    })
    .catchError({ (error) -> Observable<Bool> in
        return just(false)
    })

This returns just fine and I get the data.

My new request is exactly the same but the only difference is the provider and requests are using the second TargetType. For this one, the requests never takes place (confirmed with Charles). I have checked the TargetType and it looks just fine and performing a non-Rx Moya request works fine, so does an Rx request where I subscribe to it.

Why doesn't it work using flatMapLatest?

I'm new to Rx and very new to Moya so any help is appreciated.

Edit: Debug messages for the first provider:

Refresh token -> subscribed
Refresh token -> subscribed
Refresh token -> Event next(Status Code: 200, Data Length: 773)

Second:

Refresh token -> subscribed

Nothing else

Make sure you retain the provider or the dependency chain that it holds somewhere. I've had an issue with retainment in the past.
