Hi need some help, i got error for the suspend function transactionAwait : "suspend function can be called only within coroutine body".

callRealmSuspend { realm ->
            realm.transactionAwait {
                realm.delete(RegionRealmObject::class.java)
                realm.delete(ServiceRealmObject::class.java)
            }
        }

and my callRealmSuspend function looks like this:

suspend fun callRealmSuspend(call: (realm: Realm) -> Unit): Realm? {
    var realm: Realm? = null

    try {
        realm = Realm.getDefaultInstance()
        call(realm)
    }  catch (error: java.lang.Exception) {
        LogHelper.e(messages = *arrayOf("Unhandled error occurred: ${error.localizedMessage}."))
    }

    return realm
}

so how do I change callRealmSuspend function to fix the error/ provide a coroutine body? thanks!

you just need call: *suspend* (realm: Realm) -> Unit)

thanks a lot @Tijl !

Or make the function inline, since you call the call lambda directly from the callReamSuspend function.

thank you @streetsofboston! that's a good solution as well
