hi, am I missing something or is this a bug?

val list = listOf(1,2,3,4).k()

ListK.monadFilter().fx.monadFilter {
    list.bindWithFilter { it % 2 == 0 }
}.let(::println)

crashes with NPE. But this works fine

val list = listOf(1,2,3).k()

ListK.monadFilter().fx.monadFilter {
    list.bindWithFilter { it % 2 == 0 }
}.let(::println)

that looks like a bug in bindWithFilter

Would you remind reporting it? thanks.

[than_]

Sure 🙂. Just wanted to be sure.

shot in the air but the bind continuation is advancing the iterator to a point where there is not ore values and then it tries to access the value in the predicate

[raulraja]

just guessing

[aballano]

this is an interesting one indeed, I’m taking a look 👀

just got a fix, it’s gonna be fixed in the next release https://github.com/arrow-kt/arrow-core/pull/134
