Hey all! I have a coroutines question that I've been struggling with. I am making a network request in the following way:

fun fetchCharacterData(): Deferred<CharacterGenerator.CharacterData> {
return GlobalScope.async(Dispatchers.Default) {
val apiData = URL(CHARACTER_DATA_ENDPOINT).readText()
CharacterGenerator.fromApiData(apiData)
}
}

Then, in my main activity, I do the following within `onCreate()`:

generateButton.setOnClickListener {
GlobalScope.launch(Dispatchers.Main){
characterData = fetchCharacterData().await()
displayCharacterData()
}
}

However, I am getting an ANR whenever the button is pressed. I also get a very vague error message in logcat: FATAL EXCEPTION: main.

Would anyone have any insight as to what the issue could be?
