I want to pass an error exception to my paging adapter via callback.onError(or callback.onRetryableError) in loadInitial or loadafter but always receive crashes. After some debugging I find this in library sources:

It's actually what I'm receiving in my crash trace. Just "todo". Dependency version:

'androidx.paging:paging-runtime-ktx:2.1.1'

Does it ok to have such kind of exception message on production at all or I did something wrong? Anyway... Question: any other 'builtin' ways to pass loading error to adapter?

Well, in 2.1.2 instead of fixing it they just remove onError & onRetryableError at all. – once2go Mar 21 '20 at 16:42
it is terrible when the page load failed, it did not give any method. – Lenoarod Mar 25 '20 at 10:42
