On line 11 I am getting type inference failed not enough information fun<T: Any!> error( exception: Throwable!): Single<T!>!

pls, replace first string and database[id] fo val elt = database[id] ?: return Single.error(Throwable(“Not found”))

[Denis A]

database[id]!! is very bad case

[zone]

thank you. Will keep that in mind. The main problem is it's not compiling in flatmap returning return@flatMap Single.error(Throwable("")) giving error

[Dominaezzz]

Is it fine with Single.error<User> and/or Single.just(database[0]!!)?

[zone]

now working with Single.error<User>

[Denis A]

I don’t understand, why do i need use flatmap in this example
