hey channel.
I need to iterate a map and create a new map but with a transformation in the key. I will replace a value in the key based on the original key.
I am trying to do in this way but the compile complains of

fun pathMapped(): Map<String, String> = paths.entries.iterator()
    .forEach { entry -> return mapOf(entry.key.replace("__","/"), entry.value)}

could someone else here help to do implement this in a correct way?

fun pathMapped(): Map<String, String> = paths.mapKeys { (k, v) -> k.repace("__","/") }
