Androidjava.lang.IllegalStateException：必须在主线程上调用方法addObserver

尝试访问视图模型时抛出异常。异常抱怨调用 addObserver，但我在代码路径中没有看到任何可能调用 addObserver Fragment 的内容

@AndroidEntryPoint
class ReferralEntryDialogFragment : DialogFragment() {
private val viewModel: ReferralEntryViewModel by viewModels()
override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
super.onViewCreated(view, savedInstanceState)
binding.applyCodeButton.setOnClickListener {
GlobalScope.launch {
try {
// Exception is thrown as soon as viewModel is accesses
// It does not get to applyCode function
viewModel.applyCode("code)
} catch (e: Exception) { }
}
}
}
}


视图模型

@HiltViewModel
class ReferralEntryViewModel @Inject constructor() : ViewModel() {
suspend fun applyCode(code: String): ApplyReferralResponse {
val result = Firebase.functions.getHttpsCallable("applyReferralCode")
.call(mapOf( "referralCode" to code))
.await()
val map = result?.data as Map
val jsOnString= Gson().toJson(map)
return Gson().fromJson(jsonString, ApplyReferralResponse::class.java)
}
}
