I have the following functions : ```fun interface ...

I have the following functions :

fun interface PatchDevice<T> {
    suspend operator fun invoke(
        deviceId: String,
        payload: T
    ): Either<Error, Action>
}

fun interface PatchDeviceAttribute<T> {
    suspend operator fun invoke(
        deviceId: String,
        payload: T
    ): Either<Error, Action>
}

suspend fun <T> save(
    patchDevice: PatchDevice<T>,
    patchDeviceAttribute: PatchDeviceAttribute<T>
) {
    either.eager<> { 
        val patchDeviceResult = patchDevice("")
    }
}

The IDE complains that Restricted suspending functions can only invoke member or extension suspending functions on their restricted coroutine scope when I call patchDevice() What should I change to make it work?

[jean]

Is the only possible way to fix this by removing suspend from both interfaces?

[raulraja]

Remove .eager from the either block. Just either { } will work with suspension

So I ended up with a compilation error when doing this. I’m not really sure what’s going on though : https://youtrack.jetbrains.com/issue/KT-52540
