is there any way to handle the nullability of the api response, I tried to use default values in the model, but not sure Retrofit use them in parsing the model to Rx

This is a perfect example of how you can make great spaghetti using rx. This should return a single and the whole logic can be done in a simple map.

[Mohamed Ibrahim]

where is the spaghetti, could you point it out

[Paul Woitaschek]

Imo all these operator chaining makes it very hard to follow the logic flow

[Paul Woitaschek]

The toObservable things make it even more complicated. Also the firstOrError()->onErrorResumeNext is complicated because it builds the control flow based on exceptions

[Paul Woitaschek]

Also a function named build and a string called params doesn't let me know what's happening here

[Paul Woitaschek]

From the code I'd say it should be called phoneNumberOfPrimaryDeliveryCourier and maybe even return a PhoneNumber class

[Paul Woitaschek]

I'd write it like this: https://gist.github.com/PaulWoitaschek/3f7ea0627de22b739f16ecb4eecc07bd

I agree with some things, maybe the multiple map operators could be one but still you will need to check for the Nullablity which was my first question.

[Paul Woitaschek]

But the nullability of what?

[Mohamed Ibrahim]

backend response retrieve Nulls

[Paul Woitaschek]

Didn't show my refactoring how to handle null?
