Hi. The problem is somewhere you are getting null value. Put debugger and check where you are getting null value and resolve it. Follow this video for example, https://youtu.be/GwtevbSLuXQ

Hello, I'm dealing with the same problem. Can anyone find a solution?
Dim obj = New Fare_InformativeBestPricingWithoutPNR()
obj.passengersGroup(0).segmentRepetitionControl = New SegmentRepetitionControlDetailsTypeI(1) {}
obj.passengersGroup(0).segmentRepetitionControl(0) = New SegmentRepetitionControlDetailsTypeI() With {
.quantity = "1",
.numberOfUnits = ("2").ToString(CultureInfo.InvariantCulture)
}
obj.passengersGroup(0).travellersID = New SpecificTravellerDetailsTypeI(1) {}
obj.passengersGroup(0).travellersID(0) = New SpecificTravellerDetailsTypeI() With {
.measurementValue = 1
}
obj.passengersGroup(0).travellersID(1) = New SpecificTravellerDetailsTypeI() With {
.measurementValue = 2
}

Check the existence/null check of _TravelFlightInfo.unitNumberDetail before using it. I think _TravelFlightInfo.unitNumberDetail (being an array/list is not initialized in the first line of code.
