Kotlin Flow - Android: Application gets stuck in flow combine and does not move ahead

I am trying to combine two flows and then send the value to a function and then collect the result.

My code never goes to second line of combine and never comes to collect results block.

What am I missing can anyone pls explain.

Below is my code:

viewModelScope.launch {

            combine(flow1, flow2){ model1: Model1, model2: Model2 ->
                performAction(model1, model2)
            }.collect {list ->
                updateState {
                    copy(isLoading = false, list = list)
                }
            }
        }

Code never goes into performAction function and progress keeps loading.

Please help

I'd suspect that one of your flows is actually empty.

Could you ensure that both of them are emitting values?
