I'm not sure if this is an issue with AndroidX Navigation kotlin safe args pluging ( or something missing on my end), But I get a stackoverflow crash when relying on the generated code 🧵

[Marco Pierucci]

This is the generated directions class

public class WorkOrderParentHeatPumpSurveyFragmentDirections private constructor() {
  private data class WorkOrderParentHeatPumpSurveyFragmentToEditRadiatorsMeasurementsFragmentAction(
    public val roomRadiatorData: Array<RadiatorData>
  ) : NavDirections {
    public override val actionId: Int =
        R.id.WorkOrderParentHeatPumpSurveyFragment_to_editRadiatorsMeasurementsFragmentAction

    public override val arguments: Bundle
      get() {
        val result = Bundle()
        result.putParcelableArray("roomRadiatorData", this.roomRadiatorData)
        return result
      }
  }

  public companion object {
    public fun WorkOrderParentFragmentToCaptureBarcodeFragment(): NavDirections =
        ActionOnlyNavDirections(R.id.WorkOrderParentFragment_to_CaptureBarcodeFragment)

    public fun WorkOrderParentFragmentToCaptureCameraFragment(): NavDirections =
        ActionOnlyNavDirections(R.id.WorkOrderParentFragment_to_CaptureCameraFragment)

    public
        fun WorkOrderParentHeatPumpSurveyFragmentToEditRadiatorsMeasurementsFragmentAction(roomRadiatorData: Array<RadiatorData>):
        NavDirections =
        WorkOrderParentHeatPumpSurveyFragmentToEditRadiatorsMeasurementsFragmentAction(roomRadiatorData)
  }
}

WorkOrderParentHeatPumpSurveyFragmentToEditRadiatorsMeasurementsFragmentAction

Its referencing itself thus causing teh StackOverflow

[Marco Pierucci]

This is not an issue if the java gradle plugin its used

Sounds like you need to stop TitleCasing your actions and IDs

[Marco Pierucci]

Hmm yeah probably, the codebase was not using safe args yet so there was not an issue before. Interesting edge case
